The Apple iPad Review (2012)
by Vivek Gowri & Anand Lal Shimpi on March 28, 2012 3:14 PM ESTThe Next iPhone
Historically the iPad has been the launch vehicle for Apple's next-generation iPhone SoC. It's safe to say that the 45nm A5X we've seen here today won't be finding its way into a smartphone. Instead what we're likely to see in the next iPhone this year is a 28/32nm shrink of the A5, coupled with Qualcomm's 28nm MDM9615 instead of the 45nm MDM9600 enabling LTE support.
It'll be next year before we see the introduction of the A6 in the fourth generation iPad, which will likely bring ARM's Cortex A15 to the table as well as Imagination Technologies' PowerVR Series 6 (codename Rogue) GPU. Apple isn't done driving GPU performance. There's still a chance we'd see the introduction of a Cortex A15 based SoC late this year for the new iPhone but I still believe the timing is too aggressive for that to happen.
Haswell
In working on this review, Vivek IMed me and told me the best part of using an iPad instead of a notebook is the battery life. When the battery indicator reads only 20% left, chances are you've still got a good couple of hours of battery life left on the new iPad. On a MacBook Pro? You're lucky if you get half of that.
The question is, must this gap always exist? The MacBook Pro has much more power hungry silicon, and it's running a much more power hungry OS and application set. I won't go too far into this but one of the promises Intel is making with Haswell, its 2013 microprocessor architecture, is for a > 20x decrease in connected standby power. Intel's goal is to be able to deliver an Ultrabook in 2013 that can remain in connected standby (still receiving emails, Twitter updates, push notfications, etc...) for up to 10 days on a single charge.
What about for a lighter, more tablet like usage model? Will Haswell be able to deliver more iPad-like battery life for most tasks, but offer the horsepower and flexibility to run a traditional OS? I'm hearing very exciting things about next year...
Windows 8
A while ago I made a list of the top 10 things I did with my computer. It looked something like this:
Web Browsing
IM
Photo/Video Editing
Excel
Editing Reviews (HTML)
Publishing Reviews (FTP, CMS access)
3D Gaming
Writing
Email
Twitter
Of that list of 10, most of them could be done on a tablet, but only a couple of them delivered a better experience on a tablet than on a desktop/notebook (web browsing and email). You could argue that interacting with Twitter is also better on a tablet as well. Regardless of where you draw the line however, the fact of the matter is that for a user like me I can't replace a notebook with a tablet or vice versa. I need both. I don't like the idea of needing both, I'd rather just have one that could always deliver the best experience possible.
It's this problem I believe Microsoft is trying to address with Windows 8. Put Windows 8 on a convertible or dockable tablet (ala ASUS' Transformer Prime), with x86 hardware, and you've got a very real solution to this problem. When you want a touchscreen tablet, you've got one. When you want a more traditional workhorse notebook, you've got one there as well. I make the x86 reference because that way you don't lose out on compatibility with all of your older desktop apps that you may rely on.
For years Microsoft has failed to deliver a consumer friendly tablet by forcing a desktop UI on it. Its experience with Media Center taught us all that vastly different usage models need different user interfaces. It took Microsoft a long time to realize this, but with Windows 8 I believe it has one solution to the tablet problem. It is ironic/funny/depressing that with Windows 8 Microsoft is simply making the same mistake it made for years with tablets, in reverse. This time around the desktop experience suffers (or at best, just isn't moved forward) in order to focus more on the tablet experience. Sigh, one of these days they'll figure it out.
The point of this sidebar on Windows 8 is to talk about the iOS equivalent. Apple advocated so strongly with the iPhone for the consolidation of devices, I can't help but assume that we'll see a similar move in the MacBook Air/iPad space. iOS is far more multitasking friendly today than it was a couple of years ago. The support for multitasking gestures alone on the iPad is huge. But there clearly has to be more. I don't even know if iOS 6 is really when we'll see this intersection between tablet and ultra portable happen. Like Haswell, this may also be a 2013 thing...

I use it every day. But it don't see enough improvement in the new version, to warrant an upgrade. I view the high ress as an actual downgrade. As the machine will have to upscale the majority of the content.mavere - Thursday, March 29, 2012 - link
text text text text.If that means nothing to you, then the upgrade won't do anything for you. For the rest of us, this screen is a godsend.
darkcrayon - Thursday, March 29, 2012 - link
I'm guessing the machine will have to upscale very little content other than images on the web in a month or two. Every major app will be updated for the higher resolution, no new app will be caught dead not supporting the new resolution, and text based apps get a "free" upgrade to the higher resolution. If your primary concern is whether images on the web will be updated, then that's an area for disappointment. Otherwise...adityarjun - Thursday, March 29, 2012 - link
I love this site and most of the reviews. Since the ipad has been released I have been coming here 6-7 times a day just for this review. Glad to see it finally put up. I just registered here specifically to ask a few questions.While I was more than impressed with the review, I was hoping to read something about the use of Ipad as an educational tool. This section was sadly missing.
I am a engg grad student and I am currently looking for a good pdf reader. The only viable options for me are the new Ipad or the Kindle DX (the kindle 6" is too small). While the Kindle does sound good , the problem is that some of my pdf books are over 100mb and full of mechanical drawings. Will the Kindle be able to handle that, especially if i want to frequently jump pages or refer to multiple books side by side? I have never seen a Kindle in person so anyone who has used it, please comment.
Reading ebooks on my laptop is a pain. I often read through the night and that is not possible for me to do on a laptop. The vertical height is too small and I often end up turning the laptop 90 degree to read. Not to mention, carrying around a laptop in your hand is impossible for long durations. Plus the zoom options on Adobe reader are just weird. In short, I am really uncomfortable reading on a laptop. I have tried both a 14" 1366*768 screen as well as 17" 1920*1080 screen
On the other hand, ipad gives me the advantage of iOS. I will also be able to see OCW videos on the ipad as well as watch my college slides (ppt). Ipad owners please comment-- can i play .avi or real media player file on it directly or through an app? I can also use the educational apps like Khan academy plus it can serve as a note taking device. The disadvantage of the ipad is that reading on it through the night will probably leave me blind in a year or so. I have myopia and my power is -8D. That is one BIG disadvantage, or so I have read. I have never used an ipad so perhaps someone who uses it can share their experience of reading on it for hours at a stretch.
I am really confused about this so I hope the collective intelligence of this site will help me make an informed decision. And I would really like to see a page in the reviews of tablets that talk about the reading and note talking abilities and the educational purposes they can serve.

I understand your desilusion with the ommission here of any specific discussion of the advantages or desadvantages of using the iPad as a book reader. After all, that may probably be one of the main usages of the iPad, apart from browsing the web or checking the email or Facebook posts. But anandtech.com is mainly a tech site for geeks and technically oriented people, and we must understand that putting a special emphasis on specs and speeds is more interesting for the majority of its readers. For an analysis of your question, you could perhaps go into one of the various sites that deal with ebook readers. Unfortunately most of them, as far as I can tell, have not the level of expertise or care that anantech.com has in its analysis (see http://www.the-ebook-reader.com/ipad-3.html as an example).Now to your questions. I have no direct experience with the new iPad or the kindle DX. I have an iPad 1 and a kindle 3 (the one with the 6" screen and no touch controls). I haven't seen yet the new retina display of the iPad, but from what I've been reading it's much better on text than the previous editions. I doubt however that it is as good for the eyes as the eInk screens are - these are reflective and, as such, closer to paper than LCD screens. From my experience - I'm an intensive reader and use glasses, due to my advanced age - eInk screens don't put as much stress on the eyes as the emissive screens do. If you are planning to read through the night with a LCD screen use an indirect ambient light and plan for frequent periods of rest.
On the other hand, handling pdfs on the Kindle is an awful experience. A DX is certainly better than a 6" one, no doubt, because the bigger screen allows for larger type. On a 6" screen you can forget pdfs. You can't read them. If your typical pdfs can be accommodated in a 9,7" screen without zooming, then a DX can be the eReader for you. But be careful with the illustrations: I think the DX has the same controls that the 6" non-touch kindle. If that's the case be prepared for a bad experience with the illustrations, specially if they are detailed and need zooming (or if they have colour). The DX is a non-touch machine. The iPad touch controls are much better.
You can't see two documents side by side on any of these readers: not on the iPad and not on the Kindle. For that you need a laptop. On the iPad you can use a trick: open one document in one app (say, on the eBook app) and the other in other app (say, on the kindle reader). By switching rapidly between them, you can see the two documents in rapid succession. You can't do that on the Kindle. But this is a trick, a compromise, and not the same thing as looking to two documents side by side.
As to seeing ppt's and videos, the iPad is the way to go. There are apps for that. The kindle has not that capability.
In the end, my advice is this: try to get access to an iPad before buying, and see if it meets your expectations for reading clarity and comfort. Getting access to a DX before buying may be more difficult, because there are few people around with them. I have yet to see one and they are around for several years.
I'm sorry if these considerations haven't been useful for you.

See this YouTube analysis of the Kindle DX with pdf's: http://www.youtube.com/watch?v=bVPBCD0GgBw&fea...adityarjun - Thursday, March 29, 2012 - link
Thanks you very much for your reply.It does seem as if neither of the two fit my needs perfectly. So I will have to make a compromise.
A 6" kindle or 7" tablet is out the question. It is just too small to read comfortably on.
The Kindle DX's screen and size seemed good to me but if you say that it can't handle pdfs comfortably then it is of no use to me. I will not be viewing any newspapers or magazines nor will I be surfing the net with it.
The only other option that remains is to use the ipad. The pros is that it should be able to handle large pdf *as per videos on youtube* as well as all my videos.
The con is the eye strain.
Is it really as bad as some sites make it out to be? Especially when compared to an e ink reader?
I will try to get my hands on an ipad and use it for a day or two but come to think of it, the screen cant be that much more stressful than a normal laptop, can it? And I have been reading reviews of the SoCs on Anandtech since morning...
Damn, I am really gonna go blind at this rate. *summons immense willpower and tries to close anandtech* * fails :-) *

I keep and read all my technical pdf files on the ipad (textbooks, reports, memos, drawings, etc). I use an app called GoodReader which is absolutely amazing with all kinds of pdfs.Regarding eye strain, I usually keep my brightness setting at around 50% and zoom in to make the font large, which strains my eyes a little less and definitely less than a desktop screen. The sharp font on the new retina screen helps as well. That said I will admit it is not as easy on the eyes as an e-ink display.

Honestly? I think the iPad's screen (even the first iPad, let alone the new one) gives me significantly *less* eyestrain than eInk, and I've owned a couple of Sony eInk readers.For me, the key eyestrain issue between the two is contrast. eInk displays are a light grey background with dark grey text, and in bright lighting the contrast is fine. But in less than bright lighting - for example, an indoor room without either a ceiling light fixture or multiple floor lamps - I start having trouble with distinguishing the text. Even a 40-year-old yellowing paperback is easier for me to read under those conditions. While you can use a clip-on reading light, I find that both clunky and less effective than it would be on paper.
The iPad (and really, any backlit LCD screen) has the 'stare into backlight' issue; but honestly, this is rarely a problem for me, and in particular it's much less of a problem than eInk contrast issues. Backlit color LCDs also wash out in bright sunlight, but not in even the most brightly-lit interior room, in my experience - however, for me this isn't a significant issue, since I spend much more time reading indoors than outdoors.
So just in terms of legibility, I'd pick the iPad (or the nook Color/Tablet) over any of the eInk readers I've used. And that's leaving out issues of software and PDF handling.
