LOL. You must be used to the typical camphone/P&S oversaturated, overcontrasty, oversharpened, far-from-natural output. Didn't you read the review? The PureView tech's goal is to produce natural, life-like image output. In any case, you can mangle it anytime on your PC to get that "Instagram-crap" look you are looking for.
Images are flat with no pop but if you're planning on dirtying it up on instagram and posting it on face book or twitter who cares.
