Wow, the first major redesign of the iPod since the first one, and I'm not counting moving the buttons to the wheel or repackaging the Nano or giving it a colour screen:
It's shiny, it's cool, it's.... An iPhone with different innards and, from the looks and common sense of it, not particularly different at that. It has WiFi, so it doesn't even go without all radio hardware. It looks like it's got a (presumably modified) version of the same OSX-lite operating system complete with Safari and, by peering closely, I see the YouTube client as well, it presumably has the same storage hardware, it's obviously got the same touch screen and, one suspects from that page and without even reading anything, the same motion-sensing automatic screen reorientation. iPhone does the music player stuff, so that's all clearly the same. It is, not to put too fine a point on it, an iPhone with the phone part excised. Maybe the microphone and speaker as well.
This is why Apple is doing so well and can offer so many cool products: They know how to reuse everything. Why develop a new case if you've got one to hand? Everyone thought that the iPhone would look like an iPod, but no, they've been cleverer than that: Bring out a new image-raising product and make the iPod look like that, instead.
Actually... If this has WiFi... and if that version of Safari can handle Google Docs... Can you get a wireless keyboard to talk to it? I'd be interested!
