I would have preferred to see it stay at $500. As Dave said 1. he might be recovering a loss 2. he doesn't intend us to buy.
For the general public they should be kept as costly as possible for as long as possible.
I know prices have & will drop more but we should still fight against it. Hopefully greed if nothing else will slow the drop.
Who knows how bad it will get when these become mainstream.
Of course its easy enough for anyone to join LPF & get in on a GB but some who only know point-click-buy just won't.
