It very much depends what you shoot. If you shoot natural landscapes, you'll never see it. (note the name of this forum, and ask why Michael says he never sees it...) If you shoot citiscapes in direct sunlight at optimum apertures, you'll see it. Grills of Air conditioners, distant brickwork, clothing of someone bang in focus at a particular distance, etc:
If you are a nature photographer, forget about it. non-issue
If you shoots textiles, or clothing, get the regular 800, non-E. why make life difficult?
If you are a all around photographer, it really depends if you are comfortable with doing retouching work on some shots, in exchange for a slightly sharper image.
