Hi, I'm in the market for either a MBA 13" or a MBP 13" but I skype and take pictures a lot using webcam so I'm wondering which laptop has the better camera? I'm sure the MBP does, but is it a noticeable difference? My current laptop has a VGA resolution webcam and it sucks. Is the MBA's camera at least as good as the frontfacing camera on the iPhone 4? Thank You.
