"it could disrupt photography by making it easier than ever for beginners to take good photos."

These cameras do not help beginners, or anyone else take good photos. In much the same way that instagram doesn't. Sure, it might be a fad, like HDR is, but nothing short of learning about composition and lighting will make anyone take good photos.

I don't see anything disruptive about lytro photography. Being able to pick the focal point arbitrarily after the photo has been taken is a cool gimmick, but what's the point? How many times have you really wanted to do that with a photo? Beginners seldom take photos that are out of focus because autofocus systems have improved so much. Most blurry photos are due to low light and camera shake, poor handling of the camera. Lytro does not solve that problem.

I hope it succeeds and becomes a viable alternative, just as foveon sensors were/are, and I hope the company do well, this is an exciting time for photography.

"Most blurry photos are due to low light and camera shake, ..."

The Lytro camera has a fixed wide-open aperture, so exposure times are kept short.

" Being able to pick the focal point arbitrarily after the photo has been taken is a cool gimmick, but what's the point?"

You can also change the depth of field after the fact. E.g., to blur out the strip club in the background of an otherwise nice shot.
