Any particular reason you're leaning towards a Smartphone?
I currently have a
Cingular 8125 and before that I had an
Audiovox SMT-5600 (aka iMate SP3) which is similar to the phone you're concidering.
The 8125 Is more like a PDA that also does phone stuff. The SMT-5600 Is a phone that also does PDA stuff.
Both run Windows Mobile 5.0 but using the phones is a drasticly different experience. They both do a decent job with windows Media 10 and the big draw for me was the ability to sync the phone's calendar with my Lotus Notes calendar.
Web browsing is MUCH better on the 8125 both becuase of sheer screen area, and the landscape screen orientation when the keyboard is flipped out.
Speaking of keyboards... there was no on-screen soft keyboard as the SMT-5600 isn't touchscreen like the more PDA like phones are (my 8125, the XV6700 etc). You're options for text entry are T9 or 111 222 etc via the dialpad.
The big thing I miss having gone from the SMT-5600 to the 8125 is the small form factor. While the 8125 isn't huge by any means, it isn't as nice to slide into my pocket as the SMT-5600 was.
I still slip the SIM into the 5600 when going out just because the phone isn't as bulky to haul around. If the phone meets your needs, go for it. Be sure to pick up a screen protector. If you go for the candybar form factor, the silicone jackets also do a good job of protecting the phone i fyou can find one for it.
