I agree with TC1, excellent topic. I love braggin about my phone. Since I'm attached at the hip (literally now, belt pouch) to my job, here's most of what I do with my Mogul:
EVDO + OpenVPN = Fast as hell access to my work network. This let's me:
1. Check on my phone system and the call stats.
2. Check all 40 (not at once) security cameras in/around the building.
3. Console and GUI access to all my servers using PocketPuTTY, VNC Viewer, and WM6 Remote Desktop.
4. Administrate all office printers and copiers.
5. Finally take a vacation away from home because of 1-4!!!
Basically I can take care of anything other than hardware failure from almost anywhere, and that makes me a happy man!!!
Not to mention streaming radio kicks @$$!
