Go for Vista. Especially if you get it free. I have had about 1% of my programs having compatability problems, but other then that it is great. I really like the software, and I think that you should stick with it. I have Home Premium that I bought on
www.academicsuperstore.com for $70 if you are a student or teacher, and I think that I got a pretty good deal. Anyway yah stick with the Vista.
