Leaving aside the angst, I was not trying for pretty.
As for clipping the case to the keyboard cover, I have done that too. Not so sure it is good for the keyboard and not a very useful answere whne I am using this as a tablet.
If I have time, there is a product I have that will smooth things out and cover the dried GOOP. I use it when I assemble plugs and the result is pretty enough to convince most that the things are made by serfs on an assembly line in China.
Of course a lot of this may go away when Steve Balmer announces the Surface Keyboard II. Also note the pen groove at the front of KB!
