I'm impressed with my Metawatch. lasts for a week, using SoWatch i get all my notifications from my N9 without taking the phone out of my pocket.

Great whilst on a bike, driving etc. It is as 'open' as you can get. There are no real 'apps' on the watch, they are all on the phone. If you can code for N9, you can get busy! If only i could be competent with github and work on @JavisPedros SoWatch work!

I don't need different 'watch faces', but it would be nice to configure the home screen as per the iOS and 'Droid phone apps.
