I'm really impressed with the Android OS ingeneral, and very impressed with motorola's motoblur.
One of my classmates was a hardware beta tester for the Devour, and I was very impressed with not only the device itself, but the operating system and the customization of the whole experience.
It's a little phone with a lot of features (especially for social networking and email)
I'm definitely thinking of making the Devour my next phone.
