What is infinite contrast ratio? Is the phone able to emit zero light from a pixel instructed to show RGB(0,0,0) when another area asks for RGB(255,255,255)? Multiple color gamuts—does the phone's screen actually extend well past sRGB, or did they just discover perceptual color mapping? The compact camera market went through a spec-obsessive phase, and it resulted in 14+ megapixel compact cameras that struggled with anything less than direct sunlight. My 12 megapixel dSLR sounds weaker spec-wise, but works better in every lighting situation—even this aging piece of kit gives me pleasing images at ISO 5,000, well past its design limits. There's a lot more to design than stuffing in faster CPUs, more RAM, and more screen and camera pixels.
