Looking at my horizontal Brain Cell, I'm bothered by the fact that the top doesn't close well, creating an impression of a poor fit with the laptop even though my Brain Cell was designed for my 13" MBP Retina. The visibly exposed velcro (resulting from the bulging-out of the top flap) is an eye sore, seriously detracting from an otherwise perfect product. I'd like to suggest improving the design by lengthening the top closure a few millimeters so that it can close the top in an elegant, flat manner.
