Apple's new "iTV" set-top box has stirred up a lot of interest -- but what do we really know about it? Macworld's guys sort through what Apple's told us so far -- and what we simply have to guess about. Unlike most Apple products, which tend to ship soon after they’re announced, this product isn’t going to arrive for at least three months. Jobs said that it’s due out during the first three months of 2007, which means it could be at Macworld Conference and Expo, or it could ship the day before April Fool’s, or anywhere in between.
