I ... *ahem* ... din't buy Vista Ultimate (I think you know what I mean by that one )
I do use tools like Remote Desktop etc. to remotely access my PC.
This is a must for me, as I often need to access the files I have from time to time.
Unfortunately products like VNC and Remote Administrator don't work with Vista and LogMein seems to randomly screw up on Vista. As for pcAnywhere, I've never bothered trying it on Vista, I doubt that it will work.
I still have one PC running Windows XP Professional though.
