One thing I do sort of lament that would have basically guaranteed this thing would smash the market: If it featured a "standard" OS that allowed it to use many of the apps and functions of a regular tablet. So many people use tablets nowadays that it would be the perfect "must-have" device. Have all your basic functions of a tablet, and now I can switch over and play high-quality video games on the go or on my TV. Imagine how well that could've destroyed the market.
But then tablet models update every other week so maybe it would've been difficult to pull off.
