Hey guys, I currently have a Casio EX-S500 and it is a 5 Megapixel camera. The new Casio EX-S600 camera is coming out with a 2X brighter LCD and an upgrade to 6 Megapixels. The main question is will I notice a difference between 5 megapixels and 6? Is it worth it for me to sell my current camera and upgrade to the 6 megapixel camera? Thanks so much!
