Windows 7 reminds me a lot of the mac os. :s LOL, Just kidding there, from what I have seen, Windows 7 is a step in the right direction. I like what I have seen. I'm still waiting for the driver updates to catch up, I went through that with Vista.Having worked for Microsoft for the better part of 18 years, I have to say that Vista was not our proudest moment. One thing that can help Vista users is to use Microsoft Security Essentials (remove other anti-virus and reboot first), very fast, well regarded and wont slow down your machine at all.
Windows 7 rocks, however, I've been using it since beta and have it on several machines, from netbooks to laptops, it really is terrific.
