I did find it useful. Sorry if I didn't make that clear before. I am considering a new 15" too and I really want the anti glare screen but I don't think these old eyes can deal with the small text on the hi res screen. I have looked at both screens along with the 17' at the Apple store and I think I have even more trouble with the text on the 17". I really wish there was an option for the anti glare with the standard res screen. I keep looking and trying to get used to the high res but I don't think I can.
Maybe check them side by side with the 17" to see which one is less straining to your eyes. I got the 1400x900 res and I still find the letters too small! Damn glasses!!!
