Wikipedia is a great source of information, and it's getting bigger every day. If you're like me, you'd be hard pressed to go a day without looking something up on Wikipedia. But sometimes you might not have Internet access -- devastating, I know! -- and you still need to know whether there's a grammatically correct sentence made up entirely of the word "buffalo." Well, it's a good thing there's Wikitaxi, an offline Wikipedia app.

With Wikitaxi, you can snag the entire database of Wikipedia -- or, if you're pressed for bandwidth, the Simple English version is a lot smaller -- and read it offline on your Windows machine. It comes with a separate importer app that you can point at a database, and then you can use the main Wikitaxi app to run searches on it. Those clever people at Lifehacker suggest that you carry it around on a USB drive: then you can prove that buffalo thing to your friends at a moment's notice!
