Xslimmer

One challenge with the MacBook Air is making sure you don’t run out of hard drive space. Enter Xslimmer which is a nice $12 app that scans the file and removes unnecessary bloat, like PowerPC files and language translations contained within each app, which can be about 50% of the overall app size.

Running it on 10 applications saved me 150 Mb of hard drive space and made them a bit zippier to boot!
