A Motorola Milestone (AKA original Droid in the US). I like it because I prefer having a physical QWERTY keyboard option, and it's a good smartphone besides. But because I live in Canada, where the big telecom companies conspire to keep us in the mobile and broadband Dark Ages, I'm still running Android 2.1 on it. If they don't release 2.2 in the next few months as promised, I'm rooting the sucker as soon as the warranty expires.
