+ Not sure if anybody else thinks this, but I would prefer to have a mechanism to lock (temporarily) the position of the screen once I have it the way I like (i.e. some kind of locking mechanism for the 2 rotating wheels on either side of the unit). I sometimes find that I adjust the position by accident when taking the unit off. Not a big deal really, but would be my preference.
+ Would also be good to have the cable guide which is on the right strap on the left strap too (my PC is on my left hand side). More cable guides in general would be good.
