It is interesting, though, as these are considerably cheaper than laptops/desktops and would be a very affordable and upgradeable solution. But I think the "3-in-1" smartphone is the future because, like the laptop, it will go home with you. A second, separate device is really not a game changer, although it may find it's niche because of flexibility and affordability. Asus Padfone is closer to that reality than this thing.
I'd consider that stick, though, if I didn't have surround sound speakers (thus I've disabled my flatscreen's speakers). Maybe some day if I decide to upgrade my receiver something like this or that chrome stick might become part of my system.
