The 17 inch MBP (from last year) AG is only about a pound heavier than the 15 inch MBP AG (and they are each lighter than their glossy equivalents). What I don't understand is how the 17 inch is seen to be so much bulkier than the 15 inch - they are both very bulky but with not much between them compared with the 13 inch. As for the res, isn't it possible with the 17 inch to make the res smaller so you can see the text easier? As for refurbed macs, is it possible to order a refurb mac and at the same time (assuming there is only glossy) ask for an AG screen upgrade or ram upgrade? Long time lurker first time poster says thanks.
