Ubuntu 12.04 and Ruby 1.9.3

I previously had installed Ubuntu 12.04 on a NetBook, and my overall impression was simply that it was more stable than its predecessor — particularly for Unity.

Personally, I follow that up with rvm --default system.  That means that while I have other Rubies available at my finger-tips, the one I generally use is the one provided with Ubuntu.
