Certainly with this kind of attention the young and trendy must be scrambling to find a new bike to not ride, and if I were in the bicycle business I'd be racking my brains over what that might be. Here are just a few possible candidates:
Cyclocross Bikes

Pros: Cool-looking, fast, versatile, single-speed friendly (Bianchi offers a pre-built singlespeed 'cross bike, so there you go) and offered by major manufacturers and boutique builders alike
Cons: Somewhat practical, which means you might actually have to ride the thing
BMX Bikes

Pros: Relatively inexpensive, single-speed, complements the skater/urban aesthetic, completely ill-suited for commuting and urban transportation outside of a two-mile radius
Cons: The embarassment when some 16-year old shows you up in front of your girlfriend
Old Road Bikes

Pros: Appealingly "vintage," can be had cheap, lots of people have the parts left over from their conversions
Cons: Obtaining information and parts can lead you into a strange, creepy, unhip and unappealing world of retro-grouchery and extremely long headtubes
Tall Bikes

Pros: Already a fixture of the trendier neighborhoods, aren't these things ripe for mainstream appropriation?
Cons: Even the most determined fad-monger has to admit these things are completely ridiculous (not to mention impossible to get into an apartment)
Unicycles

Fixed gear, no brakes!
Pros: Leaves hands free for juggling
Cons: No NJS unicycles...
