Frankly, this is why the non-retina unibody MacBook Pros are the best designed and engineered laptops on the market today. It's rugged, sturdy, practical, and of course, easy on the eyes. No component is hard to get at. The worst is probably the battery, but acquire a tri-lobe screw-driver and that even that problem is solved. This is probably my biggest complaint and fear with the new retina models (second only to the removal of ports, requiring me to buy $30 dongles AND the removal of the optical drive). In terms of design and engineering, in my truly honest opinion, the retina models are a step down from the non-retina models.
