In case you didn't see it, you can now get Live Mesh for Windows Mobile at
www.mesh.com - Microsoft's Live Mesh can syncronize all of your computers and mobile phones, up to 5 GBs of storage. This is kind of like MobileMe, but it is freeand it works. So you can now take a photo from your phone and have it instantly syncronize to your desktop OTA. You can also add files like .cab and .exe on your desktop and have them instantly sync to your phone over the air without activesync.
I have it set to back up my internal 4GB storage on my phone at all times.
Cool!
