Trust me when I tell you...if Windows 7 is not 110% stable and perfect for you, there is something wrong being done. (Speaking openly, in general to everyone.) I have months of uptimes on my P4 machines, one non-hyperthreading with only 768 MB RDRAM. I use these machines for everything, and I'm on them 10+ hours a day. It's all in the drivers and software installed (or not installed for that matter.) Windows 7 is a rock. Best I've even seen by far, and I've seen 'em all. I mean out of Windows versions. I have a little Linux experience. Not enough to praise or speak against, but with Windows 7, I honestly have no current needs to venture so much there.
