This is a cool little freeware app
for your Windows Mobile phone that will let you connect with your desktop machine to your phone to control it using a window and your keyboard and mouse. You can also capture the phone screen, drag and drop files to your phone, and connect over IP (although I haven't got that one working yet on my phone.) I can confirm that even the mouse scrollwheel works on phone apps, though it doesn't appear to pass-through video display.
But this is a great little utility for doing lots of text entry on your phone, to see the phone more clearly on your computer (you can view x 200-300%), or to troubleshoot phone problems by remoting into the computer connected to it.
