The latest USB nonsense: Neon signs

In the insane world of USB gadgetry, it's often impossible to find anything useful. And this is probably no exception, but it's at least one example we wouldn't immediately throw out. Ever since college we've had a soft spot for neon signs, though we do have one minimum requirement: that they're legible, unlike the "Bar" sign included among a trio that includes the @ symbol and a smiley face seen on GeekAlerts. But we have to ask: Is it really necessary for this to have a USB connection, as opposed to a plain old wall outlet? We seriously hope that people aren't planning to set up this stuff with their laptops while on the go--and in public.
