The Idea: Personal flight
Stage: Finally, commercially available
A New Zealand company, Martin Aircraft, is taking orders for the first commercially available jetpack. It's recreational, so you'd need to go fly in a field somewhere, rather than to work. It's also expensive, with the Martin website stating a price of $100,000. If that price comes down, however, it's not hard to imagine that folks might want to fly to work instead of drive. That is, until air traffic looks like the freeways of today.
