Here's my dilemma: I just sold off my old 17" Powerbook which I really liked, had no problems with. I have been toying with the idea of getting a new 2.4 Penryn base 15" MBP because of portability reasons (easier to take with me to Masters' classes). I also like the 200GB HDD, Multitouch and cooler temp. operation compared to the Merom models. BUT, I'm scared of the display issues. To avoid having those problems, I'm also considering a refurb 17" 2.4 Merom because it sounds like none of the 17" machines have the yellowing issue. I'd have to deal with hotter operation, smaller HDD and no multitouch. I have read thru some of the threads on the yellow banding problem and am still dumbfounded, it's very confusing. Is there any way (serial number/batch codes?) that I can avoid the yellow issues? Is Apple receptive if I take my chances, get a bad one and complain? Should I skip the worry and get a 17? Anyone deal with this choice? Thanks for any insight!
