Mac notebooks: Operating temperature The bottom surface and some areas between the keyboard and LCD hinge of your Mac notebook can become warm after extended periods of use. This is normal operating behavior.
Apple MacBook Pro 13-inch (Retina Display). It's not leather, but shouldn't it be? My current computer got me through my undergraduate work, but I don't think it's got the gusto to get me through my graduate work. If, and only if, you have a spare MacBook lying around, perhaps you could show me how well it fits in the bag!
