Concern is
1. Scratch - I read somewhere iPod nano is easily scratched. If this one has the same coating, it would be difficult for keeping the gear while maintain its watchability.
2. The screen size is 'tiny', ie 2.5 inch. In the age of big screen TV, I wonder who the real user is, ie gadget fanatic?
3. Software. So far, Apple and ABC (the US major network, not to be confused with an Australian channel) join hands so we could get famous shows

lost and desperate housewives right after the show was aired. I think it's an interesting proposition here on the program line up. Other genre of programs should be coming soon.
I think it will have its own fan but I wonder about the general appeal from the larger audience, particularly hometheater fan. Gadget guy, of course, will jump in at anything new and flashy so you could count them in, straining their eyes on tiny screens just to try to make us of its function.
