The foldable Oru kayak announced today that they're going to be kickstartering in about a week, with a price of $800.

I'm going to wait until I hear reviews about how this actually functions as a kayak, and honestly I had hoped that the price would be closer to $500, but not needing to worry about portaging or roof-racks or anything really makes for an interesting investment for a casual kayaker.
