Windows isn't going away anytime soon, but Ubuntu 7.04 is a refreshing Linux-based alternative to Vista.

Microsoft hasn't gotten off to the best start with Vista. It's slow, it's annoying, and sometimes, it's downright confusing. Linux has been around for ages but has played David to Bill Gates' Goliath for longer than we can remember. We're not predicting that Ubuntu will change that relationship, but it may be the alternative you've been looking for. Because Linux has always been a bit of a mystery to most people, we want to take this opportunity to answer the myriad questions you might have about this promising OS while sharing what we like about it and what we don't.
