They changed it because it's a bit cumbersome to use a 1" screen on its own without a strap. It does make a great watch, though.
That was my point..... It could appear that they [Apple] saw what 3rd parties did with the 1" Nano with the watch strap cases etc and rather than evolve the product into a watch they have made space for another product instead.

I don't get why this is a big deal? I charge my phone 2-3 times a day. I'm used to battery management.
Sort of defeats the point of a mobile phone if you need to stop and find somewhere to charge it 3 times a day!
