Spent half the day trying to figure out why I don't have anything in Sync Center in Vista HP and now I stumble across an old post here which informs me it's not to be had on HP! I fail to understand why this feature is part of the installed programs when it's not available in Home Premium; what a waste of time! Tried Sync Toy 2.0 to keep some personal files up to date between my PC (Home Premium) and Laptop (Ultimate) but I don't seem to be able to make that work right either; used "Contacts" for a try and files get updated from my Laptop unto the PC but not the other way around using "synchronize." Switched left and right sides for either machine, same result. I can't even use Briefcase which I got set up on an external HD connected to my PC because the personal files are under a different user name on the Laptop. At least for me, Vista has become an absolute nightmare!
