well, if you want to completely skip the PC and go straight from one device to the other, you could try
Funambol - it will take all of your WinMo info and copy it to the funambol servers. Then you can copy it back to your android device. There is a 90 day free trial - plenty of time to do what you need.
Here's more info
There's also a simple program that will only copy your contacts

Another commercial application you can look at is
CompanionLink
I still don't know what I will be using to make the switch to android yet either. I've only got about 2 weeks left though, I've pre-ordered the EVO and I'd like to have a solution ready and waiting when I get it!
