Got the cover last night!
It covers the entire lower surface.
My model of M1210 is the loaded model with all the media and camera buttons.
The cover is based on the basic model keyboard so there are no button flexes for the MediaDirect and camera buttons next to the power button. I have no problems using these buttons without the flexes though.
I was worried that the touch pad would not work properly through the cover but was happy to find it works great! No problems with any of the key travel or touch pad button movement.
There is about 1/8" of adhesive on each edge.
Been using for about 5 hours now at work.
Seems like it is well worth the money.
