Yes it is expensive, and no, I took some poetic license in the characterization of commenting on the Li-ion price as, 'whining.' I apologize if anyone took-offense at the word. For a battery which works better, I'll gladly pay more if it keeps me from being stranded, even one time. The lightness is just cool, besides functional.
I consider it similar to a reliable 'electric foot' for starting, the introduction of disc brakes on the '69 Honda 750, or electronic ignition instead of points/condenser. I think that in-time, it's going to be the standard for all but the cheapest bikes.
Guys willingly pay $2700 for a set of light, wide, contemporary sized wheels/tires, but I'm not gonna do that because it's approaching the value of my 22 year-old bike. I'll save for a Gen II instead.
