No, there are still some of us out there that do things differently !!

I sync my iphone with my Windows Vista desktop regularly, and the M$ Outlook calendar and contacts are sync'ed automatically every time the phone is plugged into the computer (which charges the phone too). It is the machine I use when I am back in the office and I keep both in sync as much as possible.

I have not worked out how to wirelessly sync anything with the iphone, I use the USB cable. I have seen that MobileMe is supposed to do this over the web when I am on the road, but have not bothered with doing that just yet!
