I'm also very happy with mine, had it for a few months now. As long as you don't care about 4G, and especially if you have wireless available regularly, you should like it.
Battery life isn't stellar but if you were satisfied with the battery on the OM this one is similar, maybe a bit worse because of the faster processor and slightly lower capacity battery. When connected to Wifi it uses much less battery than when on the data network. I don't find it to be a big issue because I'm rarely far from power to plug it in.
Although there don't seem to be any stock sized batteries available anywhere other than Metro yet (@$40 a pop!), the aftermarket does have extended double-sized batteries very cheap and they come with an extended rear cover.
I don't take a lot of pics but the camera is decent, and the flash makes an excellent flashlight with one of the flashlight apps.
Too bad they raised the price though, I got mine when it was still $129 and shortly after that it went up to $149.
