And a pretty misleading one at that. "The iPad team worked with the SproutCore team to provide native hardware acceleration to the JavaScript layer..." Yeah, that couldn't be further from the truth. MobileWebKit has had hardware accelerated 3D transforms since before SproutCore existed. And that's the only part of the entire equation that is hardware accelerated. Plus, you can also do it at the Obj-C level, it's not something unique to MobileWebKit. For many things, JavaScript on these mobile devices is fast enough. But let's not pretend it compares to native app performance. It is, in fact, 50-100x slower. It just turns out that in a lot of cases you don't really need that speed (which is true in lots of environments -- look at ruby).
