What we know: islate.com was registered to Apple in 2007, through an intermediary (to disguise its true owner). At the moment, that domain doesn't seem to lead anywhere—and there are a couple explanations. First, Apple bought it as a protective measure, to stop anyone else from using that "i" prefix with that particular word. Second, Apple had or has plans for either a product or a project by that name. Third, it's the tablet. Or fourth, it's Apple's take on Slate.com (sample headline: Why I Hate Christmas Presents). Maybe we'll find out just what that meansin January, when the tablet is rumored to be announced.
