it is almost impossible to create such library without having the hardware to test. Each time I personally create a library, I end up testing many many times before it works correctly. without the hardware, no such testing is possible. I personally would like a pebble. And if I get one I will try to create the lib for that (if needed). The original smart watch by Sony was deemed very buggy at best. I looked at getting one a few months ago, but didn't see one good review.
