Which one will make more heat and more noice, between newest MBA and MBP? MBP: 15inc retina, 2.3GHZ i7, 8GB w/ flash-drive. MBA: 13inch......., 1.8GHZ i5, 4GB w/ flash-drive. Compared with: 1. Little use (few fans on browser + mail + skype). 2. Normal use: watching a video, playing and old, simple game (asking for pentium 2 or something like that). 3. Hard use: playing newer game, watching HD video. thx for you comments.
