This week in Las Vegas, the Consumer Electronics Show hosted 170,000 punters and 4,400 exhibitors many of which – like Samsung – have stands the size of an airline hanger. Impossible then to sort the wheat from the chaff, but RedShark has had a go and offers up six of the best from the world’s gadget extravaganza.

Affordable 360 cameras have always had one big limitation. Resolution. All this is about to change with the KanDao Qoocam 8K, an affordable, and very small, 360 camera that allows 4K 'overcapture' output, could be the device we've been waiting for.
