I think it's an oversized ipod touch. If it came with max osx, i'd buy it.
Besides, I think there will be better options that might "copy" it in a few months (running android or windows 7 probably). I just hate the fact that Apple blatantly tells you what you can and can't use in a device you own. It's a completely closed source system....not saying it should be opensource, but it should offer options (let you install apps from unofficial appstores, or choose a different browser, etc).

I'm wondering if this device falls in the "computer" category...it'd be sweet if it gets in trouble with the EU for how they deal with this OS.
