Didn't see the specs of the wifi chip. No sync over wifi, it seems, which is a shame. Hopefully that's a software update away, as it would be cool to sync wirelessly, and perhaps even stream content from iTunes like an Apple TV.
Streaming video from iTunes like an ATV is a big reason I am starting to lean towards my netbook+OSX (which can stream from iTunes on my desktop wirelessless via Front Row or iTunes). Come to think on it, the iPad needs Front Row, period.
