Recently Microsoft gave a sneak preview about Windows 7. You can find some of the snapshot here in Flickr and watch the Introduction to Windows 7 in Channel 9
One thing interesting that I find about Windows 7 is that it is really light. I found this quote in a website that follows Microsoft closely. (Microsoft Watch).
“The senior vice president of Windows engineering continued: It has a one gigahertz processor and one gigabyte of RAM and it’s running Windows 7. And when I boot it, about half that RAM is still available today in the current build. And we’re going to keep working on that, and we’re pretty excited about the work that we’ve done on performance, and I’m pretty “excited about this class of machine and the work that we can do to deliver that Windows 7 on those machines.”
