Well, if we are going that far back (a G3), I could say that I had only headaches and countless re-installs on XP!
One of the nicest computer ever is a G3, thought. The PowerBook Pismo is still a workhorse for many out there, and it was introduced in 1999/2000. Sports one of the greatest keyboard any laptop ever had, never got warm, crisp lcd (for the time, of course in 2012, it's obsolete) and with options to either carry 2 batteries or 2 hard drives or one HD plus CD/DVD.
