My laptop uses lucid, definitely loving it and I've been running it almost a month now without a single problem. As far as the internet being slower, there's a good chance your wireless card is by Broadcom. It's not Ubuntu, it's Broadcom being a bunch of douche bags about their drivers, you have to get it directly from their site.
If steam for linux ends up being the real deal, I may end up saying goodbye to windows permenantly.
