iPad 2 is still the best idevice in the Apple roost: http://www.anandtech.com/show/4951/iphone-4s-preliminary-benchmarks-800mhz-a5-slightly-slower-gpu-than-ipad-2
yes that is true but in my opinion they are keeping the ipad 2 less useful on purpose so people still buy the 4s. From what I've read Ipad pretty much got the most stripped version of IOS 5 and won't get Siri either. In my opinion apples pretty much mocking those that bought one but then again I'm not a tablet fan.
I wouldn't say stripped down. iPad 2 has the ability to use gestures (touching the screen) to multitask, while the iPad and iPad 2 can use a split keyboard, as well as tabbed browsing. iPad 2 also is the fastest idevice for browsing, now.
the ipad specs are more powerfull than thoose of the 4s.. but this won't result in much better gaming performance due to a simple fact.. the ipad screen has a higher resolution and therefore needs to push more pixels.. around 28% more pixels.. (960*640 compared to 1024*768) so the performance on screen (not offscreen like they did in the benchmark tests) should be very similar.. and of course battery comsumption is an issue.. i mean the 4s already looses 1/3 standby time compare to the iphone 4 so everything should be fine..
I was under the impression they really stripped the music app down and it lost a ton of features (like lyrics) also I read the Ipad didn't get the notification widgets either. To me that sounds like they have purposefully stripped it down as it could handle them even better than the other devices and I can't see any reason they would do it apart from purposefully limiting it. It does seem like a strange move while they are still sellng the iPad2 but maybe their margins are higher on the 4s or their confident people will buy both.
Stripping out features is nothing new for Apple. The iPad 1 doesn't get the new gestures at all despite the fact that you could get them in 4.x by spoofing a developer account using Xcode. All of the A4 devices are capable of video mirroring at 720p by adding a single line to a plist file and yet Apple has chosen not to enable it on them. For a long time the additional sounds added to the iPhone 4 were kept off the 3GS for no apparent reason. It's kind of a shitty thing to do and I don't quite understand why they do it. I bought a HDMI adapter for my iPad 1 after I jailbroke it and enabled mirroring, now if I upgrade without jailbreaking again I'll lose that feature.
That seems extremely short sighted to me. People are not going to toss a year old product for a new model just because it has video mirroring or more text sounds. Think of all the Apple TVs and HDMI adapters they could have sold supporting video mirroring on A4 devices. The loss of those sales surely outweighs short changing a minor feature on older devices just to call it "exclusive".
Then, why if it is perfectly fine on older devices? Some people *want* video mirroring. They search and see they need to upgrade. There might only be 100 upgrades because of this, but it adds up.
