Not sure that the great guys at Lytro have captured the essence of what's brilliant about this technology. They talk about "living pictures". What they have really done is make a stills camera where you can shoot now and focus later in post production. If you have ever tried photographing during a conference, then this will be a very useful device to try. Cheapest model is US$399 in early 2012. Not ready for video just yet...too much processing power would be needed at the moment.
