SuperSite for Windows recently published a review of the latest Windows Vista beta release: build 5219. And some of the new features made me say, “Oh, sweet.” To list all of the features and improvements would mean a humongous blog post, but one that’s really worth mentioning is the ability to increase your system’s available RAM by simply inserting a memory stick. That’s right: stick in a 1GB keychain memory stick and you get another gig of RAM and an instant speed boost; an “external RAM upgrade.” Sweet.
