Re: A numbers game
I'm not sure that people are blinded by Megapixel numbers as once they might have been. Some folks happily just buy the newest Samsung Galaxy or iPhone every couple of years because they feel the previous incarnation served them well enough and life's too short. Both the high end Galaxy and iPhone phones are considered to have good camera systems, and the iPhone's camera has remained at 12 megapixels for a while now.
Of the remaining folk, some choose a handset for another feature (cost, SD card, stylus maybe.
Other numbers are creeping into phone adverts, such as minimum aperture and photoreceptor size.
