Hi all, I need to buy a notebook as I'm going to be traveling a lot for the next year. I've narrowed it down to the 15"/867/combo or the 12"/867/combo. One of my BIG questions is: Is there that much difference in the airport reception between the two? I understand the 12" has A/extreme and is better designed then the 15" reception wise. Is the reception on the 15" models that much different?
