I've
written before about
PortableApps and
MacLibre, which offer free, single downloads that deliver bushels of top-notch open source applications to Windows and Mac users, respectively. With them, you can almost instantly populate a computer or even a USB thumb drive with useful applications ranging from
AbiWord (word processor), to
Blender (animation and graphics), to
GIMP (graphics), to
Adium (instant messaging), to
Cyberduck (FTP client), to
Firefox (browser).
As DownloadSquad notes, Windows users have a similar free option in
Smart Installer Pack. ?Here's what you get for free with it.
