Awesome, and Apple is in a position to do it. Imagine pushing down bits of the OS (or even common app functionality) to silicon! But to voice a heresy: is more performance needed?
I played with an iPad 2 last week, and it doesn't feel any faster than an iPad 1 (apart from occasional pauses disappearing). Now, this isn't a fair test, because there wasn't any new software on it that took advantage of the greater performance.
Will that software appear over time? Games will certainly find a way to use it; but it's very striking to me that the iPad 1 was so well engineered that it didn't seem to suffer from any performance problems. And the software didn't seem to be lacking. Of course it's a truism that people will always find a use for more processing power - but it doesn't seem to be true any more. Computers are now fast enough for most people. Even new game console generations are coming less slowly; the wii has less power; people are preferring laptops, netbook, iPhones, even though they have less power than desktops. That means that the extra performance isn't of absolutely crucial importance. Maybe it's nice to have - but once something is fast enough, you don't really notice if it's even faster.
Is it really possible that the iPad has already overshot the performance that the market requires? Is there an iPad app that makes you think "this thing is so slow, it's really irritating to use! If only it was a bit faster..."
