The one thing I didn't like about OS X was the lack of virtual desktops (though they will apparently included in 10.5). Now that i'm mostly using Windows I was pleased to find out that XP supports them via Microsoft PowerToys for Windows XP - the implementation isn't as good as the ones found in a linux distro, but's it's still nice to have.
A couple things I learned from the trip: if you're driving south from San Francisco on highway 101, you will pass a billboard advertising Ubuntu - what has the world come to? And Steam sucks, I had downloaded the Half Life 2 demo awhile ago and thought i'd check it out this weekend, but my parents only have a dialup connection and I couldn't be bothered to find a phone cable and set it up. I really like the concept of steam and the potential for online distribution of games - but seriously, I need a net connection just to play a free demo of a game?
Also, I find ">this video combining a Dick Cheney speach with quotes from Scarface is well done, and pretty much sums up how I feel about the vice president.
I'm glad 10.5 will integrate it a little bit better.
