A few months ago we got a hands-on with the Openmoko WikiReader and today they just announced a 2010 Update. The palm-sized electronic encyclopedia that puts Wiki in your hands is still kind of useless to those with iPhones and any other smartphone but for those folks that love their knowledge accessible in a minute, the latest update features an improved on-screen keypad that makes finding Wikipedia entries easier and faster and now also has math equations within Wikipedia’s more scientific articles. WikiReader owners can download the update for free, or, for $29 purchase two pre-loaded microSD cards per year complete with updates.
