The Apple iPad 2 Review
by Brian Klug, Anand Lal Shimpi & Vivek Gowri on March 19, 2011 8:01 PM ESTThe Web Browser
The iOS UI isn't the only area that doesn't get an update with the iPad 2, the core apps also remain untouched. Mobile Safari on the iPad 2 is effectively the same browser used on the iPhone 4, just on a larger screen.
Web page compatibility is generally pretty good on mobile Safari, with the obvious exception of any website that requires Flash. Apple continues its firm stance on not supporting Flash and hoping the rest of the world will convert to HTML5 or iOS apps. I'm personally not a huge fan of Flash, however I do believe the lack of Flash support is frustrating on the iPad. For most usage it's not a problem, but missing Flash is yet another reason why the iPad can't be an exclusive travel companion for me. There are still far too many niche sites out there that require the use of Flash. And if I'm in a hotel room with only iOS devices and no notebook, not having anything that can run Flash is a problem.
I ran two compliance tests on mobile Safari: Acid3 and the HTML5 Test. Acid3 is near perfect with the exception of an errant box in the lower right hand corner of the final test image:

In practice I have noticed more rendering errors and browser issues in Honeycomb than I have under iOS 4.3. There's one particularly nasty Honeycomb bug that I've encountered several times that prevents web pages from loading entirely until you kill the Browser process and restart it.
In iOS 4.3 Apple increased the performance of its JavaScript execution engine significantly. The result is pretty astounding. According to SunSpider the iPad 2 is now slightly faster than the Motorola Xoom, however BrowserMark puts the Xoom well ahead of the iPad 2. Google is extremely adept (and aggressive) at optimizing browser performance, this is one area where I'm not entirely sure how well Apple will be able to keep up in the long run.
JavaScript execution is only one aspect of the total performance equation however. Scrolling smoothness has been a staple of iOS and the iPad 2 does not disappoint here at all. Google made huge improvements in going to Honeycomb, but browsing in iOS is still smoother on the iPad 2.
Web page loading performance also proves to be quicker on the iPad 2, although given Google's advantages in BrowserMark it's clear that this won't be the case for all web pages.
Performance isn't everything when it comes to web browsing, and one area where Google maintains a significant advantage is in its support for tabbed browsing. Mobile Safari still requires that you tap once to bring up an array of browser windows and then once more to select the window you want to view. Apple limits you to a total of 9 browser windows.
The web browser in Honeycomb on the other hand implements tabs just like a desktop browser. Tabbed browsing has a profuse impact on usability, not unlike what we saw on the desktop (when was the last time you used a browser without support for tabs?). The fact that Apple still hasn't implemented tabbed browsing on the iPad is unacceptable.
Apple handles all memory management within mobile Safari for you, so if you happen to leave too many windows open and the iPad runs out of memory iOS will simply evict some of those web pages out of main memory. On the iPad 1 this was more of a pain as it only had 256MB of memory and a 1GHz Cortex A8 CPU, web pages were evicted more frequently and took longer to load when you went back to them. The iPad 2 doubles memory size to 512MB and loads web pages around 50% faster than the original iPad - making the experience much better overall.

The Xoom review was really written from the perspective of an iPad alternative, while I felt like we covered much of what made the iPad 2 different in our preview and wanted to focus on the bigger picture in the review.The Xoom's multitasking and notifications I believe make it easier to integrate into my workflow, but still not perfect. However Apple has been ergonomics than the Xoom, seemingly better (non-Flash) webpage compatibility, better stability and a smoother UI so it's a tradeoff.
Personally, I'd probably carry the iPad 2 thanks to improved ergonomics (especially with a smart cover) and non-smooth UI frame rates do bother me. But given my workflow neither is sufficient for me to use exclusively when traveling. That's why I mention that both camps have things to work on, whichever gets there first should get your money if you're really on the fence.
Take care,
Anand

How do you get to the number in the chart? It would make sense to use the average of all 4 displays, but you don't seem to do that:406 + 409 + 352 + 354 = 1521
1521 / 4 = 380,25 ~ 380
Am I missing something here?
Also, the contrast should be 861:
966 + 842 + 778 + 859 = 3445
3445 / 4 = 861,25 ~ 861
Black levels should be better however:
0,42 + 0,45 + 0,49 + 0,41 = 1,77
1,77 / 4 = 0,4425 ~ 0,44

The point of having the numbers separate was to show the difference between the WiFi and "WiFi+3G" versions.Death666Angel - Monday, March 21, 2011 - link
And my question wasn't about that at all. The numbers in the actual charts they use for comparison against the iPad1 and the Xoom are not corresponding to any of the 4 distinct iPad2s. So I was wondering where they got the numbers from, if they averaged them or whatnot. If they did average them, then they made a few mistakes in the process. :-) If they got them through some other means it would still be interesting to know which they used.buff_samurai - Sunday, March 20, 2011 - link
speaking about workflow.
I am running a small consulting company for food/pharma industry, my expertise is in analytical instrumentation. Right now I'm using a beefy PC for CAD/backups and IP4/ipad for everything else: emails, project management, crm and documentation all squeezed into a small and portable device (terminal).
Although I am not 100% happy with exchange support in iOS, security, syncing etc I see myself more efficient then ever and that simply means more time/money in my pocket.
Lets try a common scenario: in a car, take a call, pull over, grab a laptop from a bag, power up, check some details, email couple of pdfs and do all that with customer hanging on the phone. Repeat the whole thing 10 times or more - you will see where I am coming from. Or try to carry your laptop around any mid size production line, control room and boardrooms and impress other engineers with questions like: 'where can I plug my laptop' at the same time.
I can understand that for most of heavy laptop users ipad is just useless but lets face the fact that there are millions of professionals on the road and all they care for is better response time and flexibility.
I could spend hours listing applications where no PC (portable or not) can match a tablet but the bottom line is: when moving to new tech we need to overcome our habits first. ipad, xoom and other are like a nice and shiny screwdriver but you will never find a use for it with pockets full of nails. That means no reviewer should ever comment on any device without actually making it a primary tool for couple of months: and if there is no time/money for it - just focus on things that are traceable or you may use your reputation.

I always love Anandtech reviews, they cover 'everything' really well, advantages and flaws with equal gusto.Thanks!
Two points:
1) Page 19 I think you're referring to iDisk, not iDrive. Doesn't really matter unless someone trys to Google it.
2) With regard to web browsing, I know you're comparing these units as shipped, but I strongly recommend pro users consider 'iCab' from the AppStore, I don't use Safari much anymore. Propper tabs, full screen, downloading, browser user agent ID spoofing, way more powerful. Scroll pad to quickly navigate huge pages, gestures etc. Tt's very anti-iOS in that it's insanely powerful rather than designed to be simple, but I love it, specifically options like 'open bookmark in new tab' and 'open links from different domain in new tab' very customisable, plugins, blah blah blah. Anyway. It has Desktop style tabs. I wouldn't suggest you change the article, or review this or other 3rd party browsers because it's kinda beyond the scope of the review of the device, but it would be nice if people knew there were alternatives to give a more desktop style (still sans-flash) browser.

I have really wanted an iPad ever since they were released. Several months ago I had the money (the previous barrier to acquisition) so I went looking. I didn't want the 3G version, WiFi would be fine. But I knew I would not be happy unless I got the one with maximum ram. Well in Australia that was going to cost me over AUD1,000 (I thought they were much cheaper :-( ).Just before this I had built myself a new desktop with an AMD processor and graphics card; see I'm a fan of AMD (but not a bigot). So might I be better off with a netbook rather than an iPad. AMD had recently released the Brazos range. So I started to do some research.
The result was my purchase of a Toshiba NB550D (the sexy orange one) which is a "little under-done" with the C50 Fusion Processor, only 1 Gb of memory and Windows 7 Starter. I have upgraded the memory to 2 Gb (still not enough) and installed Windows 7 Home Pro.
The Toshiba is about the same size as an iPad but is much more functional, it has all my desktop PC's apps installed (particularly my favourite text editor (EditPlus), my browser (Firefox) and all the same bookmarks, etc. etc.) so when I travel I have everything I need and I didn't need to learn how to use new software.
I still think the iPad is a great bit of gear but that's when I use the right side of my brain. My left side says "where's the value proposition?" We are all different but for me the left side of my brain always tends to win over the right side. I am very happy with "my" iPad alternative; more memory and the C-350 processor would be good (but not the larger form=factor that seems to entail). Oh! I forgot to say that the total cost of the Toshiba (including hardware and software upgrades was about AUD675 - more than AUD325 saving!

Great review. Anandtech's reviews are always well worth the wait. They are always thorough and I always learn something. I agree that it is a luxury device and it is hard to justify it for getting work done. I still purchased an iPad 1. I recently sold it to buy the iPad 2, as soon as I can find one. I do think you downplay how important the app selection is on iOS as compared to Android.name99 - Sunday, March 20, 2011 - link
Reading the summary of what all three authors think of iPad feels to me like someone who buys an iPod because it has calendar and contact functionality, and then is upset/surprised that it isn't a Palm.iPad is not a REPLACEMENT for a laptop/desktop, it is an AUGMENTATION. You use each for what they are good at. If you find yourself spending most of your time traveling and you need a full-featured computer during that time then, sure, adding iPad to the mix is stupid. But if you already have a laptop, and can afford it, iPad makes certain tasks a lot more pleasant.
For my part, for example, my primary use for iPad is reading technical PDFs using Good Reader. I could read these on a laptop, but the keyboard really gets in the way (not to mention that the aspect ratio of the screen is inappropriate). If you don't do much reading of technical PDFs, this might seem dumb to you --- but I DO spend many hours a day reading these PDFs and I appreciate a tool that does the job properly, just like a professional carpenter doesn't use a $5 saw he bought at Walmart.
The future of computing is not one device that does everything; it is multiple devices all optimized to a particular human form factor, that all work together --- an iPod nano AND an iPhone AND an iPad AND a laptop AND a desktop. Criticism of something germane to this vision is legitimate and sensible (and Apple's flailing regarding how much of the file metaphor it wants to present to users is a legitimate part of this criticism.) But complaints whose primary structure is "this device doesn't work exactly like a device I already own" is just stupid --- like complaining that a bicycle isn't a car.
It's perfectly reasonable to say that you don't have a use for a certain class of device, especially because you already use something more powerful. I, for example, have no use for a Tivo or a video streaming devices like WD Live or Roku --- I have a full-fledged computer hooked up to my TV. But it is unreasonable to go further than that, and I've observed plenty of non-techy people who are very happy with their WD Live's or Tivos.
It's even more unreasonable to complain that "Tivo sucks because it doesn't play DVDs".
Use some sense. Don't keep trying to use iPad for things it is no good at. Keep in the bedroom, and use it to read, or to look up something quickly on the net, or to play a movie just before you go to sleep. Don't be insane and try to write a novel on it.

A good business class laptop is AUD1,500+ while a top of the range iPad is AUD1,000 + here in Australia.
It seems to me when you think about the iPod with your left brain there is very little functionality that a good netbook does not do both better and cheaper. However, I would agree that when you let your right brain rule then all of a sudden the iPad becomes a irresistible thing that you must possess. Unfortunately for me my left brain clicks in when I pull out my credit card.
