I really think they appear equally sharp--there is some kind of difference between them due to the Nano "effect", and if I force myself and look at various angles, I can tell a difference, but since I'm in a home office with both facing the window (even with shades drawn), I appreciate not being distracted by the reflections. I've worked several hours on each at night, with no reflections due to the window, and I think I may slightly prefer the Nano, so, am gonna keep it. I can certainly see where this is going to be a YMMV thing, and do urge all to directly compare these in the Apple store, or somewhere.
