I sent back my High Res MBP 15" because after using it for 30 minutes I'd get headaches and serious eye-strain. Never expected it, and ordered the HR without second thought. But the HR was a real problem for me. The MacBook Pro 15" HR is 1680x1050 opposed to 1440x900, which is a 16.67% difference. The resolution on the new 13" MacBook Air goes from 1280x800 to 1440x900, that's a 12.5% increase. So there's less of a difference, but it's still going to be smaller text on the screen. Fortunately we can all try it out in the store, where many stores don't have the HR 15" MBPs.
