How fast is Windows 7? -

Can someone tell me how fast or slow is Windows 7. I ve heard that beta version (build 7000) is faster than vista and even xp!

It is not faster than xp. Those specs are in reference to the way it can handle 64bit data chunks (dumbed down a bit for you). Actual day to day working is improved over vista but still not technically as good as response time as xp. And not even close to as fast as Ubuntu or MacOSX
