Really nice
I'd like it better with a digital display.
If also stopwatch, calendar und (scientific) calculator were integrated, I'd wear this thing even though I don't need/want the music playback functionality. OMG, so many great ideas what you could do with THAT hardware on your wrist...
Are 24h battery life with display constantly on? I fear not.
In the presentation video Jobs says "you can wear it as a watch" - so why not include a decent strap?
You can clip it to your shirt cuff - no need for a strap. But OTOH - has anyone ever seen Jobs wearing shirt?
