Priced at $39.95 on both Amazon and the PRIZIX site, the Linux Diversity collection comes with complete DVD installations for both 32- and 64-bit PCs, and it includes free lifetime updates. It's available for Windows 7, Vista and XP; Mac OS X; and Linux.
One dish, multiple flavors

If you're thinking about taking Linux for a test drive, this could be a nice way to try multiple flavors in a single dish.
