Streets and Trips for Ubuntu

Hi,

My dad has a laptop with Vista on it and is having mouse trouble. He read that it is a bug in Vista. He was thinking about dumping Vista and going back with XP. He also saw that I was running Ubuntu on my laptop and liked it. The only thing that would be stopping him is that he won't be able to use Streets and Trips. He uses Streets and Trips, as well as his road atlas everyday instead of using a GPS. He has been hearing something about the government going to sell the GPS satellites to a private company, which could mean that the private companies will start charging a monthly subscription fee.

Does anyone else here use Ubuntu and have a program equivalent to Streets and Trips?

Thanks,
