Been thinking about the next laptop to replace my trusty MBP13 and was considering the MBPr15. I haven't flown for business in a while but recently took a couple trips, and in coach found it pretty tight to work on my MBP13 on those tiny seat trays with the seat rows having gotten closer together. I couldn't open the screen quite wide enough to look directly at it, though it was sufficient to be able to get work done. Also, the trays didn't adjust so the base was coming off the edge. Who here flies with their MBPr15? Can you work on the seat trays or is the machine too big for that? Thanks!
