Ubuntu Suprised Me

I recently installed Ubuntu Linux on an older Intel Celeron machine and I got Automatix up and installed codecs, apps, and so forth. I've got to say that it is wonderful. It could be a bit faster if I ran in on my main machine, but works faster than Windows. I used a very, very simple Autmatix install.
One of the easiest I've found only three Terminal Lines. I'm really thinking about switching from Windows XP on the Main machine I'm using now and goto Ubuntu. The main reasons I'm not is: 1. I've customized every thing on the computer now and to start over, I just see no point. 2. My ATI card is having problems with Ubuntu. 3. There are so many apps that work on Windows and not Ubuntu. 4. I'm also waiting to see what Vista is going to be like. I guess I should read this article again.
