Now that's interesting! I wonder if this daily edition keeps the sharp contrast of 505? I was really tempted by prs-600 until I saw its side-by side comparison pic with 505...
The daily edition looks promising though...bigger, but not too big (9.7" big XDDD). If the sharpness is anywhere better than prs-500 (the model I've got), then it will definitely be my new machine!
