I want to get a DSLR. Am eyeing a particular model. Someone asks me (and I have no doubt more people will ask in the future), "Why you want to buy 6 megapixels? Nowadays got 8 megapixels already what...."
Is there a convenient/easy way to explain the differences between a DSLR and a compact/prosumer camera? I'm kinda tired having to explain the concept of sensor sizes to laypeople every time they ask me the same question (which usually follows "your camera how many megapixels?").
What would you do/say?
