Another vote for a Mac. My laptop did something weird at the Marriott in Copenhagen, and after that I couldn't get it to boot up at all. There is a discussion board on the Apple support forum; once we got on the ship, I posted on that and a nice man in London walked me through the fix. Voila! All I had to do was start it up with one key held down, and it basically fixed itself.
Macs are just the ultimate.
