I really don't give a damn about his philosophies, in this case his views are certainly bull heaviness and yes laziness. It is not an impossible task to come up with an attractive yet useful solution.
Beyond that this so called design philosophy gave us the original Mac Books AIRs with their trap doors. One can not twist that into good design, in fact the market totally rejected the hardware. There is a balance between art and usefulness. The new AIRs acceptance in the marketplace has a lot to do with design that is acceptable to the users.
What it took to create a machine that also qualifies as artwork was the antithesis of "lazy".
You are so wrapped up in the Johnny love fest you fail to see where many of his art projects have failed in the marketplace, mainly due to the design. Now I'm not here demanding perfection because if you don't screw up once in a while you aren't trying. What I object to is the lack of objectivity seen in these forums and the defense of really bad design at the hands of Johnny and his crew.
The slot it HAS is no harder to get to than one on the front would be.
That depends upon a number of factors including how you have the unit mounted.
(Not to mention that a front loading card-slot would require two hands to use ... one to insert, the other to keep the screen from tilting when you do so... one hand will do with the edge loading slot.)
Try a little harder please.
