I'd say the iPod Nano is the only device Apple has really screwed up in terms of a consistent message. First it has a clickwheel, then it doesn't. Oh look there's a camera, and now it's gone. It's small enough to stick in a watch wristband - but wait, now there's a touchscreen and it sorta looks like it runs apps except it doesn't.

Totally incoherent. I loved the first few generations with a clickwheel, they were great to use on the go. I have no idea what the point of the latest model is.
