Apple OSX 'invents' Apt
At today's Apple conference, one of the big roll-outs is Apple's new Mac Store.
Basically, its a way to use aptitude on OSX, for paid apps.
Debian has had apt and aptitude for a long time, with or without graphical frontends, allowing users to search for, install, and update software to their Debian OS. Other GNU/Linux Operating Systems have had their own package managers for a number of years now as well.
