I'm thinking of using Ubuntu in my car PC because I only have one copy of XP and that's being used on my desktop. I don't want to fork out cash to buy another copy of XP because most of the ones I've seen here are about AUD $70 and I've already exceeded my car PC budget. Anyway, Linux plays audio and video files fine, and that's the main thing I'll be doing with my car PC
Ubuntu Mobile looks interesting. I'd like to get my hands on a copy.
