Yes... but this is true of many, if not most, "modern" electronic devices. Manual or mainly mechanical tools and devices have looser "operating" tolerances. For instance, you can use a hand shovel until the blade is worn down to a nub and it will still perform to some degree. A gas hole auger will last as long as the motor holds out but once that goes out, it's sort of hard to twist that auger bit into the ground by hand. Electronic devices like modern TVs, DVD players, microwaves, AND digital cameras, operate on a much finer margin. If one circuit breaks, the entire device can be easily rendered partially or totally inoperable. The degree of disability depends on the importance of the circuit. The problem is, the number of potential failure points is immeasurably higher than in most mechanical devices.
This is one reason I am personally leary of lenses getting too fancy electronically. I don't care if a lens is a little slow or noisy focusing because it is driven by the camera. Once the motor and electronics are in the lens our lenses will begin to have a similar lifespan to our digital bodies... NOT GOOD!
On the other hand, assuming high quality circuitry and construction, and a little luck not to have a critical component hit by a cosmic ray, modern digital devices can last a long time. They certainly will last longer than most people use them for. The usaul "reason for replacement" with modern electronics is to get new or improved capabilities, not solely or even primarily because the earlier device failed.
(for those of you who've read other recent posts by yours truly, the reason I keep using digging and augers as examples is that I am getting ready to have to dig about 50 fence post holes... LOL)
