Re: Metr no
It doesn't say if the growth is in Apple or Wintel devices, nor that they are touch screen AIOs, so can't really conclude anything about metro.
As devices spread throughout the home, the appeal of not having wires for LAN, mouse, keyboard, video, speakers, power leads for monitor, and base unit make them far more acceptable to the overseer of gadgets in the home, in my case its the WAF, but YMMV. Whilst you can reduce a traditional PC somewhat with wireless mouse and keyboard and Wifi, you can't get beat the AIO footprint.
What is frustrating is that the dreadful sound of large flat screen TVs pretty much mandates the purchase of a soundbar, if not a full AV 5.1 system, which then adds to the cabling :-(
