Enough already on waiting for the Rev B. - I have to get something and am back and forth between the 15" and 17" MBP. What is the build quality on the latest 17" production runs? The 17" sounded as if was having the fewest number of problems and there were some surveys that backed that up - not sure how valid they were though. Most importantly - did the 17" ever receive a revised mlb to address the whine and heat issues? Those issues were less pronounced with the 17" but still a problem. Also - has the "floppy display" hinge issue been improved? Thanks.
