I'd have to agree. Windows 7 64bit is definitely the best version of Windows when it comes to 64bit. I've setup 2 of my computers with it already, 1 Ultimate and 1 Pro, and they both work great. I'm going to convert 3 more computers this weekend. There are only a few features that Ultimate offers that aren't available in Pro, so you may want to review the differences to see if you really need ultimate. Here's a good overview of the different features available each version. http://www.winsupersite.com/win7/win7_skus_compare.asp Of course, if you're not a Microsoft partner, then you'll have to wait until October 22nd to get a copy.
Yes you are true, but without Vista, Win7 wouldn't be as revered as it is. Vista had to be the whipping boy.
