Android tablet + boombox = Vizio Portable Smart Audio
4.7" or 7" tablet integrated into boombox-sized, battery-powered speakers, so rather than having to rely on the limited range/fidelity of Bluetooth or the ecosystem and AC power requirements of Sonos-like systems, it's like you have a battery-powered speaker dock with a permanently attached tablet. I'm looking forward to being able to play any thing that I can get from a normal Android device, but I wonder if I will be able to control it from another device.
