The trouble with watching video on mobile phones is that their screens don't tend to be big enough to let you get any idea of what is really happening. So all you get is a poor reproduction of the footage – some of which is now starting to approach decent quality – which you have shot.

One solution is to offer mini projectors that can hook up to mobiles and then display the images on any light coloured wall you might have handy.

At CES Microvision is touting a prototype of a ‘pico projector’ it calls ‘Show.’ It is basically a handheld, battery powered unit which can project video from everything from your mobile to your iPod. The unit itself is tiny – it is just 7mm thick – and has a battery life of over two hours.
