Microsoft has also announced they will be suspending the 2.5 million download limit which was originally going to be imposed. The information came via blog post from Windows Communications Manager Brandon LeBlanc.
Due to an enormous surge in demand, the download experience was not ideal so we listened and took the necessary steps to ensure a good experience. We have clearly heard that many of you want to check out the Windows 7 Beta and, as a result, we have decided remove the initial 2.5 million limit on the public beta for the next two weeks (thru January 24th). During that time you will have access to the beta even if the download number exceeds the 2.5 million unit limit.
I downloaded the beta on Friday and have been testing it over the weekend. Installation is pretty straight froward and should be easy enough for an average user. I haven't had any stability issues, still as with an beta software its recommended that you don't rely on it for day to day computing. Microsoft and TechNet have a great Windows 7 Forum, that can help you out if any issues arise.
I've been working on my review over the weekend and will have it up before mid week. I will say that I don't feel Windows 7 has lived up to the hype I've seen on some sites. It looks and feels like Vista SE.
