Throttle-by-wire

I've noticed more and more new bikes going to a fully electronic throtle-by-wire  system.  Does this bother anybody else? The only benefit for this over standard cables i can think of would be a slightly cleaner bar appearance.  What happens if the sensors that control these systems get a little moisture in them and either won't register any throttle input or, more dangerously, won't register the fact you've rolled off the throttle?  How expensive is it going to be to replace the throttle position sensors in relation to replacing a frayed cable?  If the system quits on a desolate stretch of highway, can you rig the electronic system to limp the bike to civilization the same way you could a bike with a cable?  I just don't see the advantage of this.  

Kawasaki has been using the throttle-by-wire system on some of their bikes for quite a few years now. So far, the only problem I have seen routinely mentioned is calibrating the throttle position sensor to eliminate the slight ping under heavy acceleration.

Like any system where electronics replace mechanicals, it can't be easily jury rigged in the field, but it reduces the failure rate from improper maintenance considerably.

It's a personal choice. Most people will be glad to have one or two less cables to lubricate and adjust. Does your bike still have manually advanced ignition timing?

Actually, it's a question of what you lose when you go to throttle by wire(TBW).
You lose the thrill of dealing with a motor that suddenly won't decelerate because that's the cable that snapped.

The feedback is easy enough to do, simple spring on the the throttle to push it to idle.

I have TBW on my car, and I've really never noticed the difference, except that on 1 car, some dirt did lock up the throttle. Quick pull up on the lever under the pedal, and it broke free.
