I posted this to Facebook...
...but with 90 minutes to go before the announcement, here's what would excite me about this Mactablet thingie. One of the rumors has it having video out. If it has that and a digital audio out, then this could be the device I've been looking for, an Apple TV that would actually work, but also would run other apps like the Sunday Ticket app and the MLB app. I don't see any reason why this can't be part of the device and it would make me want to find a way to buy one somehow...
