The Apple iPad Pro Review

At this point it probably goes without saying that Apple Pencil has been one of the major points of focus for this tablet. With the iPad Air 2, I noted that a proper stylus and keyboard would go a long way towards making the iPad more productivity focused. It turns out that Apple’s solution to the stylus part of the equation is a custom design that they call the Apple Pencil.
As best as I can tell, this stylus is at least somewhat capacitive-based. If Apple’s marketing material is accurate, it mentions a change from the 120 Hz sampling rate of the capacitive touch screen in normal use to 240 Hz when the stylus is detected. In addition to simple touch, the stylus measures pressure, azimuth, and altitude. When discussing azimuth, we’re basically looking at the angle that the stylus makes with the plane of the display, while altitude is the angle that the stylus makes relative to the normal of the display.
Charging the stylus is pretty simple. Included in the box is a female to female Lightning connector, so you can use a Lightning to USB cable to charge the stylus with either an AC adapter or a powered USB port. Of course, there’s also the case where you’re trying to charge the device on the go, in which case the stylus can be charged directly from either the iPad Pro or an iPhone. A lot of people have pointed out that this is a rather inelegant method of dealing with charging on the go, but given that the primary method of charging is through a Lightning connector I don’t really see any other solution to this problem, especially without compromising the ergonomics that come with the current design. Charging the stylus happens quickly enough that I never felt that it was a limiting factor in usage.
Apple Pencil itself is a comfortable instrument to write with. Unlike most styluses on the market designed to fit in a tablet or smartphone the body has a sufficiently large diameter that gripping it isn’t difficult for extended periods of time. The pencil also has an uneven weight distribution, which means that it won’t roll off of tables, though not so uneven that it's noticeable in the hand. The one problem worth noting here is that Apple Pencil is glossy plastic. After extended use I noticed that finger oil and lint had a tendency to produce an uncomfortable sensation. A matte soft touch texture may make more sense here, but that would introduce additional issues with the finish wearing off with extended use.

Of course, the important part here is writing with the stylus. Although I’ve already discussed the application of note taking in class before, in the time since my initial remarks on the iPad Pro I decided to do an entire project report on Apple Pencil in order to get a better feel for the stylus and its usability. This was done for a digital logic project in which we were required to draw out finite state machine diagrams, truth tables, block diagrams, and other portions of the design. I would estimate that over the course of this project, I spent at least 4 hours a day using the iPad Pro for 2-3 days.
One of the most immediate observations I had was that in some ways, the iPad Pro with Apple Pencil is far and away superior to pencil and paper. Even using the rather spartan Notes app this became clear. There were multiple cases throughout this project where a change that would have been difficult to make with pencil and paper was relatively simple to do so with Apple Pencil and the iPad Pro. For example, in cases where extra precision was needed it was possible to zoom in to erase a portion of text precisely. When an erasure was done poorly or on accident, reverting it was trivial as well. The project report, which eventually spanned 16 pages in length was synced to iCloud and was accessible from laptops and smartphones, which meant that it would be difficult, if not impossible to lose accidentally. It’s also noticeably more convenient to carry around an iPad Pro rather than a folder filled with paper. Along the same train of thought, drawing long truth tables with the straightedge function of the Notes app is much easier than carrying around a ruler everywhere. It was also great to have the project requirements and the notes application open side by side, which meant that there wasn’t a need to print out the project spec.
One notable problem that I did encounter with the Notes app is when the work I was doing spanned more than one page/sketch. An example of this would be cases where I would have to construct a state table based upon a state diagram that was sketched based upon the project requirements. If the state diagram was on a separate page, then I would simply have to switch back and forth between the two sketches or save the relevant sketch as an image to view in the gallery application, which felt a bit clunky.
The other issue, as it turns out, was getting the sketches off of the iPad Pro onto my laptop once I was ready to turn my work in. On the plus side, because all of my sketches were already digitized there was no need to locate a scanner and generate images or PDFs. However, the Notes app felt noticeably constrained in terms of export options. For example, there was no way of turning the 16 sketches I had drawn into a PDF on the device. I also discovered that as of iOS 9.2 attempting to save all sketches as images was broken as only 5 of the 16 sketches were saved to the gallery. Exporting the sketches by attaching them to an email was also unacceptable as the email export resolution was nowhere near native resolution. In the end, in order to get all of the sketches I had made off of the iPad in full resolution I had to manually select each sketch and save it to the gallery, before uploading all of the images to Dropbox. From my laptop, I could then put all of the images together into a PDF or some other acceptable format for submission.
However, despite these issues I found that the iPad Pro was remarkable for doing what very few tablets have really succeeded at. The iPad Pro actually feels comparable to pencil and paper to the extent that I never once felt like I wanted to go back to pencil and paper while doing the final project. Both the display and the stylus have sufficient resolution to the extent that precise work is easily achieved. The feel of the stylus feels like a good pen or pencil, without odd weight distribution problems.
Latency is also exceptionally low compared to most consumer solutions. Out of curiosity, I borrowed a Wacom Cintiq connected to a Macbook Air with an Intel i5 4250U CPU (Haswell 1.3/2.6 GHz) to do a basic latency comparison. Using Adobe Photoshop on the Wacom Cintiq and Adobe Photoshop Sketch on the iPad Pro and a high speed camera, I attempted to characterize latency by using a simple pen tool (3 px, full flow) by measuring the delta in time from when the pen was at a specific point and when inking reached the same point.
Stylus Latency - iPad Pro vs. Wacom Cintiq | ||||
iPad Pro (Photoshop Sketch) |
Wacom Cintiq (Photoshop) |
|||
Latency | 49ms +/- 4ms (3 frames) |
116ms +/- 4ms (7 frames) |
After a few trials I measured an approximate latency for the iPad Pro of roughly 49ms or 3 frames of delay, while the Wacom Cintiq in this configuration had roughly 116ms or ~7 frames of delay. It’s worth mentioning here that the camera I used was recording at 240 FPS, so these figures could be off by around 4ms even before accounting for human error. Although the Cintiq 22 HD does have higher latency, I wouldn’t put too much into this as it’s likely that a more powerful computer driving the display would narrow, if not eliminate the gap entirely.
For reference, I estimated the Surface Pro 3 to have about 87 ms or 5-6 frames of delay, and the Surface Book to have about 69 ms or around 4 frames of delay. However, in the case of the Surface devices I was using Fresh Paint, which is a drawing application that isn't exactly comparable to Photoshop but is sufficient for comparison purposes. To give an idea for how much the application has an effect on latency, the Apple Notes app has roughly 38 ms or around 2 frames of latency from when the stylus tip passes over one point to when the inking reaches the same point.
While not strictly hardware, the software equation is really a critical part here as there are actual applications for the Apple Pencil which make it possible to use right now. An example of this would be OneNote, uMake, and Adobe Comp CC/Photoshop Sketch. Some of these applications work shockingly well like Photoshop Sketch, while something like OneNote feels relatively sparse by comparison as pretty much the only thing you can do with the stylus is draw simple lines with pressure sensitive thickness, with some automatic conversion of drawings to basic geometric shapes. With the right software, I can easily see the iPad Pro completely displacing traditional note-taking in light of obvious advantages that would come with OCR and digitizing notes for easy search.

"I beg your pardon, Miss Taggart," he had said, offended. "I don't know what you mean when you say that I haven't made use of the metal. This design is an adaptation of the best bridges on record.What else did you expect?”
"A new method of construction."
"What do you mean, a new method?"
"I mean that when men got structural steel, they did not use it to build steel copies of wooden bridges."

The question around the iPad Pro is not is it a close enough copy of a workstation to do workstation work, but does it enable new work streams that were previously unexplored. As has been previously noted, the Surface Pro 4 is an extremely capable piece of hardware that checks all the same boxes as the iPad Pro, but no software had been designed to take advantage of it's unique form factor - it's still using a wooden design on a steel bridge.
The real differentiation for the iPad Pro is iOS, and the touch first / mobility first design mentality it brings to the table - software has to be written specifically for that environment and usage case. There are some notable hardware and input difference between the iPad Pro and previous iOS devices - time will tell if they can be combined to provide real productivity improvements vs previous designs or if they are merely novelties that will be quickly forgotten. Jury is still out on that, but if anyone can build the "critical mass" to jump start that exploration it's Apple. Hopefully some apps come out and wow us - to channel Asimov, there is a single light usage case advancement, and to progress it anywhere is to progress it everywhere.

I simply cannot figure your complaint: "It is a computer, REDUCED to an accessory, which COULD be THAT MUCH MORE USEFUL."So what do you want? You want the iPad Pro form factor running OSX? You want the ability to plug in a second screen? You want to be able to install Windows?
Your complaint seems to be "this is not a Surface Pro 4". It isn't MEANT to be.
It's meant to be a larger screen version of an iPad, for those for whom an iPad is an appropriate device. If you're not one of those people, WTF does it matter to you? Do you hang around bicycle tracks telling everyone there they should be using a motorbike or a car or a truck because those are more powerful?
You are stuck in a certain vision of what a computer is "supposed" to be, every bit as much as IBM confronted by DEC couldn't imagine a computer that wasn't a mainframe, then DEC confronted by Apple, Atari, etc couldn't imagine a computer that wasn't a mini, then in 2007 people couldn't imagine a pocket computer.
If you want to think of this as an "accessory" to a Mac, go ahead. I don't see what the value of that analogy, or why it's supposed to be an insult (Apple grew to the company it is today on the back of that accessory, the iPod...). People loved their iPods, they love their iPhones (especially the way they work together seamlessly with their Macs), and I expect they will love their iPad Pros.

Actually it is being touted as surface competition. Apple PR pushes this as a laptop replacement and its pricing is right with the Surface. Totally valid to compare the two.Constructor - Saturday, January 23, 2016 - link
You can do that. And Apple does indeed propose it as such – among very many other things, quite a few of which are actually better served by an iPad than by a conventional notebook.Just one example among many: The ability to simply use it in portrait mode already makes a huge difference for anything document-related, for which the narrow widescreens on computers are woefully inadequate.

Indeed it is. And it's way better than a Surface Pro, because it runs an OS that is actually designed to be used with a touch interface, while the Surface doesn't....Relic74 - Saturday, February 27, 2016 - link
Windows 10 was designed to be used with touch as well, it's silly to even think otherwise. People who such things have never used one before, simple as that.The Hardcard - Friday, January 22, 2016 - link
It's not about now. Yes now I have a laptop for things my device can't do, and a desktop for things my laptop can't do timely.But I am excited that soon devices that can be carried and pocketed will soon be powerful enough and have the software to do every thing I want to do in a timely fashion.
The iPad Pro marks the beginning of the final stage of the mobile transition, being THE computer for all mainstream activities.
There will still be larger form factors, just as there will still be mainframes. But most homes and many business won't have them.
In fact, that is what IBMs new angle is. The occasional or particular high-power computation you need done elsewhere, results served to your device. Most people won't even need that

Conditioning I guess. Some people can't imagine that using the right tool for the job is more important than using a form factor that was originally designed for media consumption.Ananke - Friday, January 22, 2016 - link
Pros use Oracle, SAP, Cytrix for 98% of hardware, and some other exotic stuff amounts for the 2% left...Hence, nobody will approve capital expense of $1000+ on software unsupported device, when a $329 workstation can just do it. Software companies don't bother to bring the huge databases to exotic silicon either, when there are already CHEAPER well developed alternatives.Tablets are great for POS terminals, some apps that require mobile high quality visual content, and that's it pretty much. There is just no functionality need for something else, especially an expensive one.

In the office where I work, the iPad Pro may be the device people have been looking for. All of our remote application access goes through Citrix, with the most-used applications being Outlook for e-mail, Word for document review/minor editing, and Adobe Reader for PDF viewing. The experience on the iPad currently is not great, because the desktop versions of these applications do not translate well to the touch-first environment. The stylus and keyboard cover, coupled with the enhanced resolution, could make a difference.It is not a solution for everyone, but I have been fielding calls from our users already about wanting these, so there is potentially some kind of market to cater to here. I realize that from a technology standpoint there are more powerful alternatives and that there are other ways to approach the software situation, but at the end of the day, this is the kind of device that our users want: an iPad with a slightly bigger screen, responsive stylus input, and a keyboard cover in a convenient package, not to mention the implied prestige of Apple product ownership (in some circles the image is considered very important).
Time will tell if this is a fad or a long-term product line strategy. If Apple can turn a profit with these (and they do have a history of turning a profit on their devices), even in spite of a limited market appeal, they will probably keep marketing them.
