The whole maintenance issue is way overblow(at least for Shimano hydraulic discs). the shop I work at sells a boatload of Shimano disc bikes, and we rarely have any bike that need to be bled after they are sold. Replacing pads and rotors is a simple job that any home mechanic can do,
SRAM hydraulic brakes are a little more problematic, but they are getting better
