Just like in a head-to-head race, you may have better acceleration, but I have the top speed...
That said, this is about ecosystems...not just hardware shootouts. By moving with Xoom I'm assured of seamless continuity with my persona in the googlesphere...however as I watched Steve Jobs announcing the iPad2 I could not help but wonder how I have to have Apple TV to wirelessly stream video, how Flash is a goner, how FaceTime only works with Apple devices etc...in other words having overwhelmingly Apple-centric features. In a way having a more open development environment (as with Android) does have its advantages as you are assured that if you need seamless interaction with another hardware device you can simply create it with the free SDK or just download it pre-made.
