Today, I've installed the extra RAM I've been promising to do for I don't know how long. I was very pleased with myself... despite the fact that it turned out to be very easy indeed. I've started round 2 of sorting out things in my study, AND I've calibrated my screen - I don't really like calibrating the screen because although it only takes a few minutes I have no patience and it seems to take hours to me. Anyway, it's done so the computer is fast and beautiful now.
