We're only about five weeks away from Christmas, so now's as good a time as any to talk about (drum roll, please) e-books. Amazon kick-started the e-book market (with apologies to earlier e-book readers) with the introduction of the Kindle in the fall of 2007. Two years later, Barnes and Noble, IREX, and Sony announced new or updated e-book readers of their own. The question becomes, which e-book reader is right for you? The truth is, they're all very similar, so it should come down to what books their compatible book stores carry. Oh, and price, of course.
