More: the cable routing on the Giant was a PITA, but a lot less than a bike with fully integrated routing. It took me over an hour to fish the rear derailleur cable through the right chainstay, and because the plastic ferrule then broke through the exit hole, I spent another fruitless hour trying to fish it out and re-install with a stronger ferrule. I would pay an extra $1 grand for a bike with full external routing.
Nevertheless, it could be worse, as with fully integrated routing and hydraulics, you could be faced with 3+ hours of hell to swap out a stem, and having to hand a customer a $300 service bill for a job that should take 10 minutes.
