Obviously, you can't use it to commute to work or school, so you're essentially buying a very expensive toy. In fact, you'll have to choose the highest tier worth $10,000 to get a unit as a Kickstarter reward. That's still insanely exorbitant, sure, but it's nowhere near its original $19,900 retail price. That said, you'll have to spend another $4,500 if you want the separate dock that can recharge it within 35 minutes. You'll likely spring for that too if you have more money to burn, because its takes SIX hours -- that's one hour per minute it can float -- to get a full battery using the charger it comes with.
