For bending note's a lot I agree, but to give acoustic simulations that real feel (saxes and guitars) and touch, there's nothing better then the joystick used on my G 800.
I do own a Kurzweil K 2600, which has a large ribbon controller and a small one beneath the pitch wheels., I wish they did put a joystick instead.
