My computer is a couple of years old and can run very slowly at times. I had to shut it down with difficulty several times in the past couple of weeks. Rather than lament the state of the economy and my computer, I took charge. I installed Xubuntu. In fact, I'm typing this post from within Xubuntu right now. So far, my only complaints are (1) no iTunes (so I have to borrow The Missus's computer for that) and (2) no Chrome. Of course, the most important nice thing is that I am having (so far) super performance. Who knew my old computer could go this fast?
I'll keep you posted, now that I can.
