Comment on OmniDiskSweeper

Another great app from Omni Group. This little app has saved me at least 3-4 GB on every Mac I own and if you buy a Mac brand new it's a great way to clean out extra printer drivers and other large files you're surprised are taking up space. Especially helpful for the new MacBook owners with only 60 GB drives (41 GB usable off the shelf).

The basic functionality is free, too. You can get the license to activate the convenient "Delete" button in the app or you just navigate in Finder and delete all the big files yourself.
