From further reading on their website, as it stands now, their target demographic is the point & shoot crowd who greatly lament all those badly focused pictures they manage to capture. ; I have also heard some ruminations that they may be working on a way to put this technology into smart phones. ; Basically areas of photography that are greatly plagued by badly focused pictures.
Also, it appears they are developing a new photo file format that will allow you to pass the pictures around and let each person "recompose" the picture using focus and lighting control. ; They didn't put a lot of empasis on it in the news pieces, but Lytro claims their technology will also let you manipulate the lighting of the photo based on all the data it captures about the light in existence.
I personally am wondering if this will be the great step I've been hoping for that helps a camera more accurately replicate the human eye's functionality in low-light situations.
But Tim is right. ; There is more to professional photography than just snapping the shutter. ; Composition is key. ; But if your target demographic is people who are wanting to capture memories (which appears to be this company's goal), composition isn't as important as capturing pictures that are not fuzzy
