At the risk of turning this into Mobile Phone morning, I'm going to talk a bit about the i730. This phone seems to have its head on straight. It's got everything: WiFi, Bluetooth, QWERTY keyboard, and nice styling. Unfortunately, there is no camera, and that might be the oversight that buries this phone everywhere except for government offices where cameraphones aren't allowed.
Carried by Verizon, the i730 even has a cute AV remote and runs Windows Mobile 2003 SE for Pocket PC, presumably upgradable as Windows Mobile 2005 rolls out. IM and email are easy to set up. I'm kind of disappointed by the external antenna, but otherwise this one is looking good.
