I picked one up today. Impressions so far:

- Comfortable. - Looks nice, I like wearing it. Doesn't feel flashy. - Does what it says it will. No buggy surprises. - Scroll performance isn't very good. - UI feels right otherwise. Nothing annoyed me. - Complementary iPhone app is well done. - Doesn't feel flimsy. Feels sturdy without feeling bulky. - Setup is simple.

No complaints so far. If you desire the features it offers I'd say it's definitely worth buying.

I'm impressed.
