In all seriousness though, I've been waiting for my Lockitron for almost a year now, and others have been waiting for much longer. At this point, there's no way I can recommend Lockitron to anybody as anything more than a cool concept.
1 year after preorder they had to process the amazon payments preorders or amazon would void them. So here I am almost 2 years since I preordered a product that I've paid for, and they can't even give me an expected ship date.
Of course they continue to send marketing emails/self congratulatory accomplishments about software updates and hardware fixes for a product that doesn't exist.
