I have a question for everyone who owns any kind of digital camera or back. Do digital sensors get old and if yes how do they age? They loose contrast? They get less bright? Which sensors are more sensitive? CCD or CMOS? When and how?

I think that we all have digital cameras now for quite some time so this topic is for us to know what to expect?

Along these lines, one thing I am interested in, is what effect intense exposure (welding arcs, the sun etc), has on fading/damaging the coloured filters that sit over each pixel.

The CCD/CMOS elements seem to be robust enough on their own, but with more digital cameras allowing continuous viewing, this may be an (admittedly minor) issue.

No real clue. What i'm sure about is that if you use a dSLR, the shutter will fail long before your sensor does.

If it is anything like my old minolta point and shoot it will just start dropping pixels over time. (Or get more hot pixels.)
