I've finished the "upgrade" from RC Ultimate to Release Home Premium on both desktop and laptop.
The only difference I've found is that Home Premium doesn't have the "Remote Desktop Host" function, which I've used for years to read the mail on the Essex machine when I'm lurking in Norfolk or elsewhere. I'd have to pay the extra £50 for Pro to get that. Since there are dozens of freeware VNC clients out there, I propose to try a few of those till I find one I like.
Anyone know of one that works well with Win 7?
