IT DOESN'T MAKE SENSE for me to pay $5000 for a Segway -- I'd get about a coupla hundred dollars of use out of it -- but it's still pretty cool. Cool, but useless. The thing weighs 83 pounds, so it'd be difficult to shlep it through the Metro. I couldn't really do more with it than go get groceries, or stop by a local restaurant or shopping center, but of course, I could do the same thing on the Metro for $2.20 round-trip, or a $1 parking plus a few pennies wear-and-tear on the car, or just walking. And who'd want to leave it outdoors, exposed to the elements, even if encrypted keys keep it from being driven away? I'm still unsure where the niche is: okay, cops who don't want to use bicycles, or warehouse personnel, or mail-carriers, or eccentric rich students at flat college campuses. (I can imagine a few of my law school professors getting one as a lark.)
