I know quite a few of you rely on my definitive pub-quiz-helper, Trivopaedia. It's now been brought up to 2008 levels, with up to date stats for v2.3 . It's available in Mobipocket reader and iSilo formats (i.e. compatible with any portable device or any platform), in addition to being fully online as well - and of course it's still free.
