Why does Airport pick up networks so differently between MacBook and Macbook Pro?

[passerbysalam]

My question is in the title. Why does it seem like in MacBook, the Airport picks up almost 3 times more networks as opposed to my MacBook Pro, which picks up 10 the most at a time?

Anyone else experience this? And why?

It probably has something to do with the size of the antenna (which is around the screen). My new iMac picks up even more than my MBP does.

Lol if you think iMacs pick up alot try an eeePC. Those ***** pick up EVERYTHING.

Is the MacBook plastic and the MacBook Pro metal? Because that would explain it. The aluminium casing interferes with the signals and so historically the "Pro" models are not be as good as the standard models in regards to detecting wireless networks. The position of the aerial could be in a different place to try and place it near a plastic part (e.g screen bezel). That would be why the new iPhones are now plastic.
Also, the age of your mac will factor in as most likely aerials improve.

Dang, I totally misread the OP!! That would of course explain it.
