I use the mStand for my Macbook Air 11 '' without an external keyboard or mouse. Nevertheless, I think the work ethic so pleasant as when the Macbook is directly on the table. I type with ten fingers system and can therefore lay my palm on the Macbook. The mStand bends here by a bit. I think but man must have no fear that because something is broken - such a small bending aluminum should also not mind in the long run. Who writes without touch typing system but will probably not be happy without an external keyboard, since it then hands then can not hang properly and it needs to keep in the air constantly.
