Ok, I've decided that I'm a Windows Mobile Junkie. Last Friday I received my latest mobile phone, the SMT5800 from Verizon (made by HTC). I really liked my last phone, the Samsung i760, but it was just a little to big and I'm not a fan of the Windows Mobile Professional SKU. The Standard SKU, in my opinion, is much cleaner and easier to use. Because there is no touch screen everything is geared toward the buttons on the phone, whereas the Professional SKU has multiple input methods which means that for a lot of things you have to pull out the stylus.
Below is a history of the devices I've had to date (except for the imate sp5 which I lost). From left to right: imate sp3i, HTC MTeoR, HTC Vox, Treo 700w, Samsung i760, and the SMT5800.
Same phones, but with the slide-out keyboards shown.
I think the SMT5800 might be the perfect phone for me. It is the Standard SKU, has very fast network speeds thanks to EV-DO, is supposed to work as a modem (haven't tried this yet), and fits nicely in my pocket. The Vox was almost the perfect phone, but the slow network speeds and slow processor bogged it down. In addition to the EV-DO for fast network access, the SMT5800 also has a 400 MHz processor making it faster than the Vox (although it still lags a little).
So I'll probably stick with this phone for awhile, or at least until the Touch comes out on Verizon. :)
