The Ewee-PT - or the Segway's "Little Sister" - is essentially a cheap way to own an awkward personal transportation system. On the plus side, you're only paying a fraction of the price to look ridiculous, er, get around faster.
The Ewee-PT can get up to about 16km/h, be folded to make it more compact and costs just over $US1000. It functions essentially the same as a Segway - lean forward to speed forward, stand upright to slow it down and stop - except that it incorporates a kind of joystick for steering. If the video isn't enough, it's available for purchase here. [Ewee-PT via SlashGear]
