I've generally been a proponent of the dedicated-function devices, carrying a cell phone for calls and my PowerBook for everything else. But some workflow changes mean I need access to email on the go, and now that PocketPCs have 802.x wireless and phone capabilities, I can avoid carrying multiple devices. I've seen the Qtek 9100 (aka T-Mobile MDA) and I really like it, but I'm wondering if anyone knows of other options? What about sites that might list and compare all the different models? Microsoft's website has very few products listed. I'm looking for something with Bluetooth, 802.x wireless, good cell phone capabilities (not Verizon), and Windows Mobile (or equivalent OS). I would prefer to have a slide-out QWERTY keyboard or none at all--the fewer buttons on the outside, the better. Thanks for any suggestions!
