Physical size is ok. Maybe if they could pull in the bezel a bit they could shrink it a little more. The bezel on the MBP isn't as important as the iPad since we don't need to hold it that way. Only thing I'd prefer is a little lighter. It's mostly the battery at this point. Kind of like the iPad. But 1.14lbs lighter than the old 15" is a good effort.
It's PERFECT !! I have been waiting on a 15" MacBook Air... this is even better. At home I used to use a desktop and also a laptop for sitting in my comfy chair to surf and email. With the iPad I sold my desk top and use a Apple display with my laptop if I am working on large reports and working at my home office. Now the new laptop is PERFECT to complete my needs. iPhone..laptop..and iPad.. Now only have a desktop at work!
