I picked one up in mid-September from the Sprint store. Here are my impressions after 1 month:
A fast pda phone--much faster than the qtek s200 and a little faster than the iPaq h6315. It is a little bigger and heavier than the s200, but the trade-off is very worth it for me. Can you say Cubis?
Obviously I have Sprint service, which required a 2-year contract. I should've argued for a shorter contract, but I just didn't care to negotiate that day. Sprint has been ok, thus far. The best thing about Sprint is that the unlimited high-speed data option is only $15 per month. That's significantly cheaper than any other provider in my area (I believe verizon was charging $44 per month, and T-mob was charging $25). So that is pretty awesome.
The phone doesn't have WIFI, which isn't great, but if you have EDGE unlimited then who cares. Unless you work in a bunker with WIFI, you won't. But then again, most bunker-housed employers wouldn't allow you to bring in camera phones anyway.
The phone can be operated fairly easily one handed. That is a huge bonus. Stylus and thumbboard input... the holy grail of PDA input is still a ways off. I don't really like using any of them. The good thing about stylus is that it is the fastest method for me when intensely computing. The negative thing about stylus usage is that it takes a toll on the screen. If you have good screen polishes then you can get rid of those inevitable scratches, so I don't worry too much. But I do like using the thumbboard for small input needs. The P key on my phone sucks, though. I can't tell if it's pressed until I have about 30 p's streaming across the text box. You know I love that.
My BIGGEST pet peeve is the absence of the one-touch voice record button. (WHY ISN'T THERE ONE? I've had one on every other PDA I've had, since the Jornada 525. Maybe I didn't have one on the Handspring Edge, but I also didn't keep that one for longer than maybe 30 days.) So anyway, I had to get a third-party application to do help me do what all my other PDAs did for me out-of-the-box. Blast!
Also, thw square resolution doesn't work that great for some programs. You get forced to scroll the extra dozen pixels on the edges to see these hidden soft buttons, which is lame.
Also, the mini-headphone jack? Why can't I fit normal sized headphones in there? Luckily I still have my s200 headphones plus the hands-free earphones that came with the phone. Otherwise, I'd be havin' be a little sit-down with the local sprint folks.
Another plus is that the phone uses a normal size SD card. That's weird--normal size card, but weirdo headphone jack. I know, I should get over it--but if they are using the weird proprietary headphone jack to make extra accessory sales, then couldn't they do it also with the mini SD card slot? I'm not complaining, I'm just trying to understand.
