Put Into Grand Perspective
I've been searching for a Mac app that allows me to see where all my precious hard drive space has gone. There is quite a nice little app called SequoiaView which is really good at that task — sadly it's not available for my beloved Mac.
Grand Perspective to the rescue! This thingie does exactly what I want it to and even looks better than SequoiaView. Well you know - we Mac people are suckers for looks.
