Though I haven't used it personally I still say you can't use all the features it offers it's just to much. As for making the switch I may but I don't have a Media Center PC per say so I cannot connect the PC to the TV without special adapters. It has a cool theme but that is no reason to switfh OS's and I also heard the Final Update Rollup was released not to long ago. Doesn't that make XP Pro more secure?
If not I may make the switch. But no adapters = no remote = no real purpose for it.
