The WikiReader (portable Wikipedia reader — see previous coverage here) is in the midst of its “Spring 2010” update, which includes new and updated Wikipedia entries, animated key presses a la the iPhone, more fluid scrolling, and “a highly requested back feature for a quick way to return to previously searched articles.”
Tech-savvy WikiReader owners can download the updates for free online, or there’s a $29-per-year upgrade plan that’ll be available for purchase sometime in the future wherein WikiReader will mail out updated microSD cards semi-annually.
