Glowplug life varies quite a bit - one of the more significant factors is the service environment of the car. Short trips mean more start-ups per mile and subsequently shorter glow plug life and more highway driving means longer life since the plugs are not used after start up (or shortly after for afterglow systems)
In my driving environment plugs seem to last for approximately 5-6 years or around 100K miles. Like a previous poster I replace them all when one fails and I've had the best service life from Beru brand plugs and the least luck with Monarck (or was it Monarch?, can't remember) and Champion brand plugs.
