Just wondering, I've never owned or seen a high res 17'' screen but I hear it can make icons and text too small? I have been made an offer on a 2nd hand high res (2 months old with guarantee) 17'' MBP. It would cost me the same as a 15'' 2.4 MBP. I dont move around much at all, maybe once every 3 months. Is this a good deal? What are your views on the high res displays?
