The difference is that there was serious room for improvement in shifting performance, but with braking the difference would only come in the form of lever feel. With braking, the best performance you can ask for is to simply have enough braking power to stop. We already have that. In this case, adding hydraulics is just stupid. A cable gets the job done without any problems and leaves nothing to be desired.
It would make slightly more sense with disc brakes, but hydraulic rim brakes makes no sense to me.
1) My 7800 shifts just fine, not sure that you need the expense of additional weight of Electric. I would think that electric would reduce the need for adjustment and my be the direction of the future. I do think you could improve the front derailleur. Red front derailleur is known to have problems and my 7800 will drop the chain every now and then.
2) With brakes you need to modulate the degree of stopping unless you go to some type of ABS system it makes no scene. A light weight ABS system would be interesting my guess it would work best with disc brakes.
3) Yes it is vapor ware and bike stuff but I find it interesting and have no interest in playing the guitar.
