I don't want electronics or anything that I can't fix on the go and service at home for cheap.
I only suffered a couple of broken cables in my life, and it's a 10 minute job to replace them providing you don't have internal routing, which is the reason why I don't like internal routing.
I don't get what's so good with electronics. Properly adjusted mechanical shifters just work and, in my experience, last a long time without having to readjust them. Plus they're way cheaper and don't require a charger and batteries.
