Hmmn. I'm pretty sold on 64 bit so I might try the x64 in a triple boot and report back if I get problems.
Maybe this latest release will have fixed some of the problems as 64 bit seems to be the way to go and I've found x64 in Windows to be much more stable than x86.
This certainly seemed true with Vista. I installed x64 Vista as soon as it came out and friends installed the 32 bit version.
They seemed to have very bad experiences, especially at first, but mine was plain sailing all the way
I was also looking at Linux Mint but I think it is basically Ubuntu in a different outfit so the latest release will be based on the previous Ubuntu release I think.
I'll give it some thought
