HTC Sync is totally worthless to me. I also ONLY want to sync with my PC and Outlook. It worked great for a few times then stopped and hasn't worked since. I contact Sprint who wanted me to return the phone, but since I always get an error on the PC when starting HTC Sync, I think it's the software on the PC and not the phone.
I called HTC support and they tried to be helpful, then said that my support ticket would be moved to a higher level and I'd get a call back in a few days. It's been two weeks, so I assume that the elevated level of support just does't exist.
Had I know of this first, it WOULD have been a deal-breaker for getting this phone. My wife has had a Pre since it came out this this was the reason I didn't get one.
I've installed all the different versions of HTC sync multiple times and nothing helps. Either it works or it doesn't work -- some people have it working and some, like me, NEVER get it to work.
I'd sacrifice a lot of features to go back to my old Treo, but I'd do it right away if I didn't have all that money tied up in this new phone.
