With a logo that resembles a purple version of a certain urban-dwelling bird, the Pidgin messaging client is a great find amidst all of the sometimes bland options in this area. Pidgin allows visitors the ability to streamline different messaging services into one device, and it works with services offered by Yahoo!, MSN, and Google Talk (among others). As with most other programs, visitors can transfer files, check their spelling, and engage in tabbed conversations. This version is compatible with computers running Windows 98, Me, NT, 2000, and XP.
