I’m going back.  I spent three and a half months on Ubuntu and enjoyed it.  I had a few problems that kept creeping up on me, and instead of working through it, I decided to just go the easy way and drop Ubuntu… for now.
It’s hard to describe the problems, but I’m sure of it had to do with my experimentation.  I just don’t have the time to troubleshoot every problem that I come across any longer.
I know Windows, and I’m comfortable just reinstalling and not having to do so much work to get things working the way they should.
Ubuntu has a little further to go before I’ll try it again, but please don’t let my experience hinder your future experience with it.  It’s much better than it was, but with school, work, and family, I just can’t spend that time any more.
