iSlate.com now Owned by Apple – the mystery deepens

He widely rumored Apple tablet, a riddle wrapped in a mystery inside an enigma, has just gotten a little more interesting.
Thanks to some crack reporting, MacRumors.com discovered that the domain “islate.com” was bought by Apple back in 2007.
What we know that: 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 few possible 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.
Maybe we’ll find out just what that means in January, when the tablet is rumored to be announced.
