The Apple iPad 2 Review
by Brian Klug, Anand Lal Shimpi & Vivek Gowri on March 19, 2011 8:01 PM ESTThe UI & Honeycomb Comparison
The iOS UI hasn't changed much at all since the iPad launched last year. Apple eventually added folders and multitasking but this is still the same basic iOS we were introduced to with the iPhone 2G. On the plus side it keeps things simple. If you're an iOS user you're likely to feel right at home on an iPad. You can then pick up an iPhone or iPod Touch and get the same experience and even run many if not all of the same apps. Apple has always done a good job of taking care of its users that don't stray from the ecosystem and the iOS universe is no different.
There are still elements of iOS that I believe are unmatched in the industry. Apple does a great job focusing on how something should work and doing its best to implement that. To date I enjoy setting alarms/reminders more on iOS than any other mobile OS I've used.
Unfortunately, the iOS UI remaining relatively constant isn't always good. The multitasking UI is still not what I'd consider ideal. Switching between apps still requires a double tap of the home button, scrolling through a horizontal list of icons and tapping again once you found what you wanted. It's basically a less convenient alt-tab.
Notifications are also horribly obnoxious. When there was no support for 3rd party notifications in iOS it didn't really matter and the simplicity of the notification system was actually a benefit. However now all apps have the ability to send you notifications and many of them will actually attempt to do so. This results in an experience-breaking barrage of popups front and center on the iPad. While multitasking allows you to switch between an IM app, your email and a web browser, if you're casually talking to someone over IM you'll find yourself interrupted by popups as you try to simultaneously read email or browse the web.
The multitasking and notification limitations in iOS are actually two significant barriers that prevent the tablet experience from actually evolving.
In contrast we have the Motorola Xoom running Honeycomb. You can argue that the Honeycomb UI isn't nearly as smooth or consistent as iOS 4.3, however Google is experimenting with more productivity oriented UIs. Notifications in Honeycomb pop up in the lower right hand corner in a manner similar to what you'd expect from a desktop OS. Multitasking isn't perfect under Honeycomb either but you have an easily accessible list of the five most recently used applications that you can get to via a single tap. Google also took a very desktop-OS-like approach to navigation in Honeycomb - the nav/notification bar at the bottom always occupies screen real estate. It may fade out when you're in certain apps (e.g. watching a movie) but otherwise it's a permanent fixture. While not quite as invasive as the menu bar in OS X or the taskbar in Windows, the Honeycomb nav/notification bar is of the same family.
While Apple has definitely stepped up its ergonomics and performance with the iPad 2, the UI remains dated. I must point out that today, two years after the introduction of webOS, Apple still has yet to offer a multitasking experience that's anywhere close to what Palm did with significantly less resources. I'm not sure if this is a pride thing or a fundamental difference of opinion. If Apple keeps up its release schedule maybe we'll be surprised this summer with iOS 5.

Considering the source (ARMflix), you need to take that video with a huge grain of salt. It looks like they're running some Linux variant on the two systems (maybe Chromium?), and while the build may be the same, that doesn't mean it's optimized equally well for Atom vs. A9.Single-core Atom at 1.6GHz vs. dual-core A9 at 500MHz surfing the web is fine and all, but when we discuss Atom being faster than A9 we're talking about raw performance potential. A properly optimized web browser and OS experience with high-speed Internet should be good on just about any modern platform. Throw in some video playback as well, give us something more than a script of web pages in a browser, etc.
Now, none of this means ARM's A9 is bad, but to show that it's as fast as Atom when browsing some web pages is potentially meaningless. What we really need to know is what one platform can do well that the other can't handle properly. Where does A9 fall flat? Where does Atom stumble?
For me, right now, Atom sucks at anything video related. Sorry, but YouTube and Hulu are pretty important tools for me. That also means iOS has some concerns, as it doesn't support Flash at all, and there are enough places where Flash is still used that it creates issues. Luckily, I have plenty of other devices for accessing the web. In the end, I mostly play Angry Birds on my iPod Touch while I'm waiting for someone. :-)

The article is indeed wrong to suggest that the A9 has only half the performance of an Atom. There are cases where a netbook with a single core Atom might be faster, for example if it runs at a much higher frequency, uses hyperthreading, and has a fast DDR3 memory system. However in terms of raw CPU performance the out-of-order A9 is significantly faster than the in-order Atom. Benchmark results such as CoreMark confirm this, a single core Atom cannot beat an A9 at the same frequency - even with hyperthreading. So it would be good to clarify that netbooks are faster because they use higher frequency CPUs and a faster memory system - as well as a larger battery...somata - Sunday, March 27, 2011 - link
CoreMark is nearly as meaningless as MIPS. Right now the best cross-platform benchmark we have is Geekbench. It uses portable, multi-threaded, native code to perform real tasks. My experience with Geekbench on the Mac/PC over the years indicates that Geekbench scores correlate pretty well to average application performance (determined by my personal suite of app benchmarks). Of course there will be outliers, but Geekbench does a pretty good job at representing typical code.Given that, the fact that a single-core 1.6GHz Atom (with HT) scores about 28% higher than the IPad's dual-core 1GHz A9s in the integer suite leaves me little doubt that the Atom, despite being in-order, has as good or better per-clock performance than the A9s.
Even the oft-maligned PowerPC G4 totally outclasses the dual A9s, with 43% better integer performance at 1.42GHz... and that's just with a single core competing against two!

Tablets do have their advantages despite what the article claims. For one thing, their battery life far out lives any Netbook or Notebook. They also run a lot cooler, unlike Notebooks and Netbooks, which you can fry an egg on. Maybe they aren't as portable as a phone, but who wants to look at the super tiny print on a phone.Tablets don't replace computers, and never will. There are nice to sit in bed with at night and browse the web or read books on, or play a simple game on. Anything that doesn't require a lot of typing.
Even a 10" tablet screen isn't real big to read text, but its MUCH easier to zoom in on text to read it with tablets. Unlike any Notebook/'Netbook, which its a huge pain to get to zoom in.

I do think the benchmarks shown here do show that there is quite an improvement over the Ipad 1, despite what many seem to claim that there isn't much of an upgrade.secretmanofagent - Sunday, March 20, 2011 - link
Anand,Appreciate the article, and appreciating that you're responding to the readers as well. All three of you said that it didn't integrate into your workflow, and I have a similar problem (which has prevented me from purchasing one). One thing I'm very curious about: What is your opinion on what would have been the Courier concept? Do you feel that is the direction that tablets should have taken, or do you think that Apple's refining as opposed to paradigming is the way to go?
VivekGowri - Sunday, March 20, 2011 - link
I still despise Microsoft for killing the Courier project. Honestly, I'd have loved to see the tablet market go that direction - a lot more focused on content creation instead of a very consumption-centric device like the iPad. A $4-500 device running that UI, an ARM processor, and OneNote syncing ability would have sold like hotcakes to students. If only...tipoo - Sunday, March 20, 2011 - link
Me too, the Courier looked amazing. They cancel that, yet go ahead with something like the Kin? Hard to imagine where their heads are at.Anand Lal Shimpi - Monday, March 21, 2011 - link
While I've seen the Courier video, and it definitely looked impressive, it's tough to say how that would've worked in practice.I feel like there are performance limitations that are at work here. Even though a pair of A9s are quick, they are by no means fast enough. I feel like as a result, evolutionary refinement is the only way to go about getting to where we need to be. Along the way Apple (and its competitors) can pick up early adopters to help fund the progress.
I'm really curious to see which company gets the gaming side of it down. Clearly that's a huge market.
Take care,
Anand
Azethoth - Monday, March 21, 2011 - link
Gaming side is a good question. Apple will have an advantage there due to limited hardware specs to code to. They are a lot more like a traditional console that way vs Android which will be anything but.Are actual game controls like in the psp phone necessary?
I am also curious what additional UI tech will eventually make it to the pad space:
* Speech, although it is forever not there yet.
* 3D maybe if its not a fad (glasses free)
* Some form of the Kinect maybe to manipulate the 3d stuff and do magical kinect gestures and incantations we haven't dreamed up yet.
* Haptic as mentioned earlier in the thread.
Speech could make a pad suitable for hip bloggers like the AnandTech posse.
