Wrong information about products.
They don't have a clue what they're talking about. They're not professionals in the Tech industry, but just TV presenters given the incorrect "dumb down" version of what the product actually is.
I particular, I'm talking about the Lytro Camera. The presenter said that it does multiple shots at different depths of field, and you can choose which shot you like the most.
This Is completely incorrect, the Lytro Camera doesn't take multiple shots, it takes one shot, but creates a 'Box of light' (hence the name Lytro).
From this 'box of light', you can choose any one focal points for a single image, or even choose many focal points from a single image, and create a mini animation/moving image.
They didn't understand the whole concept of the camera. As long as you had the correct software installed, by creating the 'box of light', you could view an image, and it would change focal points, focusing on different subjects while you were viewing it.
With taking multiple shots at different depths of field, and choosing one, as they said, that would not be possible.
