| Re: Digital Projectors
I do all my talks using powerpoint, a laptop and a digital projector and whilst the quality of a projected image can't match that of a Velvia slide through a good slide projector the versatility you gain is an enormous benefit.
With regards to lamp life - they are expensive but are unlikely to blow spontaneously, they seem to have an almost set lifespan. Each projector will have a different bulb life so perhaps that's something you might want to check. We use them everyday at work for several hours a day and in four years we have yet to replace any lamps at all. By the time we do I suspect that the price of the projectors will have come down to such an extent that it will probably be cheaper to buy a new projector - whether that's a good thing environmentally is another question.
