I'm checking my uptime from time to time, dunno why, but it's fun when I think that just a little less than month ago I had to start the windows machine every single time I used it and then shut it down. And all the silly restarts & stuff, too. This iBook was last time restarted when I updated some program, iPhoto wasn't it? Just open your console, write "uptime" and copy-paste your uptime! Mine says currently: up 8 days, 1:03, 2 users, load averages: 0.13 0.32 0.83 What are load averages, btw?
