Saw this over at Crunchgear. Amazing product with real-world potential. Small, light, and actually inconspicuous enough. Not sure how much it costs but don't think it looks to be that expensive. Plus, if it's targeted to the people who have real physical disabilities, it might be covered by insurance.
I have always had a great disdain for the Segway. I think it's a pretty useless product that got way more hype than it deserved. The fact that it's been relegated to irrelevance proves my point. Big, bulky, expensive, and more of a status symbol than an actual product. It just screams - LOOK AT ME! PAY ATTENTION TO ME! Case in point, the Woz. I don't know what it is exactly but every time I see someone on a Segway, I want to just punch them in the face.
