If I buy a car and it doesn't have just an AM radio then I will be an ex-driver. if I go to see a new movie and Cary Grant isn't in it then I will be an ex-movie watcher.

I don't get this sort of attitude. I understand loving a bike you have had but the beauty of cycling is it ever evolves and gets better in a lot of ways and some ways don't always seem that way when you haven't tried them. Electronic shifting and hydraulic disc brakes are really good and giving up on something you love because they are doing what everyone does, move ahead in time and evolve, then you aren't really committed or interested. I know back in the day I said Square taper is the best and why would I want more than 9 speeds but having tried a lot of bikes the new stuff can be quite nice in a lot of ways. Not perfect and not a reason to completely get rid of vintage bikes and equipment but having a more comfortable ride I can go faster on and shift and brake more easily with less maintenance is pretty nice.
