Jet pack that probably won't kill you

Well everyone its here, a much better jet pack http://www.wired.com/gadgetlab/2011/02/water-powered-jet-pack-runs-for-two-hours-on-a-single-tank/ , providing that you have 100 thousand us dollars, only use it over water, and go no higher than about 33 feet. Still this things have benefits: you can fly about 35mph, fly continuously for 2 hours, and being limited to 33 feet means that worse comes to worse, you fall 30 feet into water, rather than fly away and hit an airplane or a hot-air balloon. Chances are, as time goes on these things will get cheaper, and it makes me think, what will it be like when most everyone can afford one? flying across the ocean to islands a short distance away? Its 90 miles to Cuba from key west Florida, and 35 mph for 2 hours is about 70 miles distance. If they can improve these to go faster and/or last longer, you could break the embargo to Cuba with one of these things, what does everyone else think?
