Sure does.

Does the switch to 64 bit slow things down enough to explain what happened between Windows 2000 and XP?

Does the operating system have to support virtual machines? Seems easy enough to install vmware then run operating systems inside it for most use cases.

I mean, you can keep 'what if'ing me here, but, is it really worth having all the features that you, clearly as a power user or professional, use installed on every computer everywhere? No. No it really doesn't. It's bloat.
