I’ve said it many times, I’m totally addicted to QuickSilver, AppRocket is also nice for the poor folks with Windows machines. There is a GNOME application for Linux, but my POS workstation doesn’t have an updated enough version of GTK+ to get it to compile. And my Gentoo installation on the work laptop is still dead, no time to fix it any time soon.
