I've been playing with this on and off for a few weeks. My shop has their own REST development and review process. So I've been using it as an educational tool for devs new to REST, fits the bill better than swagger or postman.

Firefox OS has potential. At least you can load it onto a Nexus device, although it is extremely limited.

Trivial, but was using these irritations as an example. What isn't trivial is how poor and inconsistent the UI is (not just 7, but shockingly, 8). All OSes have warts, all companies are out to make a buck. I have been hoping MS would look at the competition and the business climate and really come up with some new ideas.

Thanks for all the great comments/responses. It really comes down to one thing: After so much time and some decent competition, why can't MS do a better job of UI? Windows 8 was their chance, and it really feels like a fancy skin on Win 7.
