I've been using 64bit AMD processors in my self-built desktops and in my first laptop. I also have been using VMware VM's, some 32bit VM's and some 64bit VM's. I've never had a problem.

However, I decided to try a 64bit Intel processor in my new laptop. Cripes!, Intel doesn't include the features in their laptop 64bit processors to run certain virtualizations. Meaning I can't run XP Mode on this machine and I also can't run 64bit VMware VM's.

Everything I do is done in VM's. So this is cramping my style.

I know this isn't a big deal for a lot of people, but it's big enough to be a deal breaker for me. This is the last Intel I'll own.
