Firstly it is rarely the case that whilst hand-flying the aeroplane any pilot will need to write anything, as "Delta737" rightly suggested.
I moved from the 757/767 to the A320/330 around 2 years ago now. At first I was very dubious about the aircraft, and the sidestick, and was unpleased at being changed onto the airbus fleet. After I began training, however, I realised that it is very easy to get used to and has many advantages.
People on this topic appear to be suggesting that fly-by-wire aircraft like the A320 and 777 do not have an autopilot disconnect button?! There is a "manual over-ride" on every aircraft as far as I know, fly-by-wire types are no exception. The only thing that is different is the way the hydraulic control surfaces are moved (via electrical systems rather than metal cables, which is a huge weight saving and has been proven to be safer and less likely to fail).
Another misconception is that if the computers on fly-by-wire aircraft fail all control is lost and the aircraft plummets to the ground. In fact all aircraft have backup control systems, and on the A320 and 777 hydraulic links are still in place allowing the aircraft to be flown in the one in a billion chance of a complete computer failure.
Fly-by-wire is the future of aircraft technology, it is like the difference between a typewriter and a word processor. Boeing entered the fly-by-wire market itself with the 777, and until a successor is found to this method of control the manufacturer will never depart from it, and no new Boeing will ever be made again without FBW controls.
(p.s. moving back to the 757/767 this March for family reasons for those who are interested!)
