Encyclopodia is software that will load Wikipedia in its entirety onto your iPod. It works with a special version of iPodLinux but has a clever dual-booting system so that you don't have to get rid of your shiny Apple interface for listening to music. You can enter text for searches using the clickwheel—not the most efficient—and navigate wiki links the same way. Amazingly, the entire English Wikipedia (German and Italian are available as well) fits in under 800MB.
