Yeah i've done it too several times and it works perfectly fine. What's really cool, is that i set up XP 64 first as the second OS, because i wanted to install vista 64. Now, i don't have a dvd drive. So what to do? I installed vista 64 from a virtual drive withing xp 64. Worked flawlessly. The only minor glitch is that i have 2 entries of Vista on the boot loader screen(i remember one other reporting that as well). This really is an amazing OS. Everthing is soooo smooth and responsive. Everything pops up instantly. It'd be interesting to be able to play with a single core and 32 bit version to feel the difference.
There are a couple of quotes from THG latest vista article that i really noticed myself:http://www.tgdaily.com/2006/12/06/rob_enderle_on_vista/
"Vista loves multi-core
and apparently screams
on both Intel quad-core and AMD Quad FX (which are also favored by early adopters) enabling what is being called "true Megatasking" or the ability to do a lot of resource intensive things at once."
That sums it up pretty well! Really is a night and day difference between this and XP.
"The part I like the most is how easily it goes in and out of suspend, like flipping a switch.
No kidding. When i first tried it, I was floored. It's like the entire OS was suspended to ram.
I wish they would have covered voice recognition in the article. It is superb.
