I just got an email from the MacUpdate.com guys saying that the first 3,500 purchasers of their bundle will get a copy of WhatSize ($12.99). I like this bonus for getting in early. I dig that.
I’ve used WhatSize a few times and it’s been useful. It is not as amazing useful as the Windows-only app DiskMapper from Micro Logic. DiskMapper’s graphical representation of files by their size is what makes it so fantasically, stupendously awesome.
