I've put my sim in and played with it for a day. It's pretty sweet, actually. They keyboard took a little getting used to, coming from a Berry. The speaker is good and loud, and mp3 playback is great. I wish it had string text, but I'm spoiled. I think all phones should do that. In general, they're flying off the shelves here. No problems yet! I was nervous about it with all the problems we had with the duo, but that was mostly based on the slow processor running windows mobile. It'll be interesting to see what happens with this model.
