Sky Mall is full of useful products, those which we ask “how could we live without?”. To wit, from my most recent travels, the following transportation products were on offer:
Carlashes (To bring the automobile anthropomorphic into the real world)

Street Strider (to combine exercise with travel, since we don’t have anything which does that already) [This is not so terrible, I suppose for the kinesthetically challenged]

Skate sail (called by Gadling the worst SkyMall product ever)

Orbit wheels
