Large 4K screens at CES 2014

Over 100 inches on a bendy TV...

Whats the market ratio for homes that could reasonably house one of them in their living rooms! 

Certainly for gaming your eyes would be 'swimming' around the screen unless you were sitting a good distance back.

River Thames to bathe in upgraded long-distance WiFi

Nice, I wonder if this actually covers the full distance of the Thames like it claims, I'll have to pop down by Kingston river and give it a test when its upgraded. I'd dubious as no matter how good your AP is, it still has to contend with the output power of the device sending back to it.
