There are quite a few threads similar to this one. But, I guess I'll cover whatever Shawn didn't.
It's running 1.6 because so far, it's the newest version of android that is compatible with MOTOBLUR. The keyboard is definitely better, without a doubt. The slide is one of the best I've ever used. It's not built for kids but is for a younger demographic just because of all of the social networking. MOTOBLUR has other aspects than social networking though. If your Devour breaks and you get another MOTOBLUR equipped phone, all you do is sign in with your MOTOBLUR account and it will load all of your contacts. That's a life(time)saver if you ask me. Not much has been done about rooting it. Though the phone may seem like the Droid, the root process most likely isn't very similar to it because of the MOTOBLUR platform. I honestly like the Droid better. The ability to root and the size of the screen really appeals to me. The keyboard is a definite drawback, though.
