Overpriced and overhyped in my opinion. Restricted to the Apple Store and what they say you can do.

Wait for an Andriod tablet, Tegra have one coming out this month. DELL have the streak and Samsung have one to be demoed in Berlin in September. Be much better value for money and being open source, your only limited by what you want to install. Will guarantee some bugger has written an app for it or get the SDK and do it yourself and earn a few quid.
