I am writing this post in Word 2007, running on Windows Vista “Pre-RC1” build 5536. The new Vista build is amazingly fast and stable. The new Word is really a great place to work. The UI improvements in Vista are wonderfully ergonomic and fun, and my laptop’s video card can’t even handle “glass.” I had expected much less from Vista, and much more disruption in Word. A pleasant surprise. I think Vista will be a compelling upgrade for the mainstream.
