I have had a very good experience with Debian amd64 on a Lenovo ThinkPad T410 for the past year. The system simply runs cooler and more quiet with than it did with x86. I've also installed amd64 on a Lenovo ThinkCentre desktop with similar results.
I have had no issues with VirtualBox, Firefox (although it was a bit tricky to find the amd64 build) or Chrome Browser for amd64. I am now only running x86 where the hardware won't run amd64. - Nate -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."
