I think it is pretty cool, particularly from my electronics/engineering background and would like to try it out sometime, but I don't see my self going for it ever. I don't race, etc. and only commute and sometimes long rides on the weekend. I haven't even updated to indexing and still ride a friction shifting, 40 year old full Campy road bike

Maybe when/if it gets to the 4th generation at $5 (per poster above), as long as it doesn't randomly decide that the rear derailleur belongs in the spokes
