Windows Phone Thoughts: How Do You Sync?

I'm using the Dell Axim X30 now as my daily Pocket PC, and with the built-in WiFi it makes synchronizing to my desktop anywhere in my house quick and easy. I was curious how you all sync, so it's survey time! I should point out that I'm thinking specifically of the desktop sync here (for files and such), not PIM sync against an Exchange server (which I also do). I'm also asking for what you do most of the time - if you sometimes do a WiFi sync, and sometimes do a USB sync, select WiFi.
