OK, the phone comes with a lot of Sprint stuff and the whole point is to be able to use the Internet, but let's stay on the channel topic and focus on the Windows Mobile part of the function.
Windows Mobile functions just enough like Windows XP to make it seem like a friend of a friend. The Start button is not there, but there is a word near the Windows logo in the upper left corner which is the Start button. Instead of saying start it says what program you are running. Once you clear that hurdle, you are back in familiar territory.
A lot of the old friends are here. Windows Media Player plays your movies and music files. There is even an Office Mobile which gives you cell phone versions of the familiar MS Office products. I can see correcting typos in a Word document or giving something the once over, but you aren't going to want to do any serious work here. It isn't the software's fault so much as the limitations of a tiny keyboard and no mouse.
The ActiveSync function leaves a lot to be desired. Like many others, I ran a Palm Pilot before I got this phone and the sync works much better there. For starters, you can turn it off on your PC. Not so for ActiveSync, which insists on running until shutdown on your computer, just in case. Even worse, by default the only option to sync your contacts is with Microsoft Outlook. Hello? Small business owner who works from a home office. I haven't used Outlook in years. What about all those other programs that have contacts?
The File Manager application works fine as long as you don't want to do something a little off key. You'll be downloading a third-party to do the fancy stuff.
Internet Explorer works fine except for the touch scrolling. It seems that I can move a tiny bit at a time (might as well use the direction button then), but if I try and scroll a page worth, it keeps scrolling after I've taken my finger off the screen and keeps going until it hits the side or bottom. Fail.
Actually, the most important feature is the least documented. In the upper right corner a drop down arrow pulls up all the currently running programs. It is necessary to hit this every so often and do a close all to keep the system from clogging up with the search you made an hour ago. It would be nice if the user could configure a shutdown after a certain period of no activity for certain programs.
