I used Fedora first, and had a lot of issues. I tried Ubuntu, and all these things just seemed to work much better, also I like Aptitude a lot better than Yum. So currently I work on Ubuntu, however as soon as Google Releases it's OS, I'm probably gonna try it out, and maybe stay at it. Because honestly, I could live with only two pieces of software, my browser - Chromium/Chrome - and Vim, so the only thing I need with Googles OS is the possibility to run Vim, and I trust Google to make it speedy, and chrash free. :)
