I have the Sprint PPC-6700 and I love it. I use it for everything from word/excel documents, surfing the net, to watching videos, and listening to music, and keeping my dayplanner. When I'm in the US I have unlimited browsing, 500 min, unlimited texting, and free pcs-pcs calls, $55 (25% discount from my employer). The customer service leaves much to be desired, and their service can be spotty depending on where you are. Check out the service area for where you'll be, some providers are better in certain areas. When I was living in NYC a few years ago I could not get service in my apt unless I literally hung out the window (and I lived on the 29th floor!), but my roomies had verizon and had no prob. But 95% of the time I have no problems.
One of the best things with the pocket pc is that I can use it as a modem for my laptop when I need to stay connected, either using bluetooth or usb. downsides of this phone/pda are that it doesn't have a sim card and can't be unlocked to use abroad
, and it is much bigger than the slim razr, but the slide out keyboard is great. I also recently purchased an external cloth keyboard that rolls small (like I said I use my phone for everything, its easier to carry than my laptop and there are offices that I have to go into and you have to check your laptop at security, but you can keep your phone.)
hope this helps.
