I've just ordered one of these (Lytro Illim). I should have it in a week or two.
Not cheap. Including lens cap, cables, extra battery, lens hood, strap, case and overnight shipping (to YouShop in Portland OR) it totals out at about US$1900. (NZ$2718-ish)....plus the $400-ish GST it will attract.
But the possibilities look awesome. I've wanted a Lytro for years.
