Windows 7 is expected to be released in October 2009. We have been testing the new operating system and although there are a few teething problems, on first impressions, it looks rather good. The layout is similar to Windows Vista but with a much improved interface. As for speed - Yes it seems faster and more responsive than Vista. Infact, it looks to be a product that will solve a lot of issues users had with the Vista OS regarding speed and usability.
If you're looking to upgrade and you want a Windows based OS - Upgrade. Windows 7 brings a much needed boost to the Windows environment.
