I love how people complain about 1680x1050 on the macbook 15.4" screen. (text and other items are too small).
Now you have companies like sony and hp putting in 1920x1080 on 13.3" screens. Imagine that straining the eyes, I think the HR on the 15 is perfect! It's the perfect combo of space, font size and res.
On the i7 model I own this was the "1" must upgrade I told our I.T guy to purchase for me. Then he went out and upgraded ram and HD as well so I'm not complaining.
I just find the 1440x900 isn't enough for the 15", plus the HR AG is amazing, it looks even better than my ACD 23" and 30". (But I think the mini display to DVI adapter isn't reproducing the colors properly).
