Yeah, I actually put a set on my commuter when I started having to go longer distances with less stopping and the bullhors weren't cutting it. It's pretty much all of the advantages of track drops without the PITA factor of narrow tops, no useful shoulders, and not being very good when forward in the drops. Also, you can pull a nice light Al pair out of the junk pile for like $5.
However, I mainly think they're going to get popular because it's the one bar style nobody is running right now, so pretty soon everyone will be on it. Kind of like how when you walk down the street and don't see any cool kids wearing Chucks, you can be pretty sure that the coolest of the cool are going to be wearing Chucks in 5, 4, 3, 2, 1...
