My two cents: The Lytro isn't a replacement for a traditional camera, particularly if you want to make big prints. However, it's a harbinger of some pretty interesting things to come, including non-traditional lenses that might bolt onto traditional cameras.

For what it's worth, I'm not getting one. If it were cheaper (say $100), then I'd get one for my daughter in a snap, since it would be a cool toy to play with.
