This will be interesting, I recently tried 11.04 and was highly unimpressed. I felt that it shouldn't have even been released. Not trying to insult, I'll keep trying, but it had problems doing even the simplest of things Windows does naturally. I installed on a USB drive and ran it from there, but I also had a folder on the drive used for storing documents. In windows, I could access the folder and do whatever, Ubuntu wouldn't even see the folder.

A few programs would not install, while some would.

The first thing I wanted to do was to install some A/V software. While there are a few, many simply stated it "wasn't needed" or "it's so secure". that is foolish, especially since I found several forums that had users testing the security of it and succeeding. It's not that I wanted to secure Ubuntu, I simply wanted something I could use to repair Windows machines, and a trusted virus scanner would have been nice.
