Ubuntu is like the Windows of Linux. So if you are looking for something that's memory effecient that doesn't crash, you were looking at the wrong thing
Which was sort of the point of the thread - to get pointed to something better.

I've installed Bodhi 3.0.0 this morning. It runs Enlightened 19. Both Firefox and Thunderbird installed without pulling in too many dependencies. Skype, though, installed a couple of hundred MB worth of extra dependencies. Now that all is installed and configured, the machine runs smoothly. There's no noticeable lag when moving between desktops, Thunderbird searches actually work again, and I can switch between tabs in Firefox without wondering whether it is going to crash.
Thanks for the suggestions!
Re. Windows XP - it would work well on this laptop, but I don't have the installation media, I don't have a valid product key, and I have no intention of paying for a solution if an equal solution is available for free. The laptop is an old one I bought over from the work, but the XP license wasn't part of the deal.
