I just received my Black palmguard yesterday. I ordered it on Saturday, so it only took 3 days to arrive.
My thoughts. I LOVE it. Installing it takes all of 5 minutes. The black blends in perfectly with the rest of the Macbook. I actually wish the whole Macbook was made with this matte finish.
I am still up in the air about the trackpad. It is a clear plastic, and I don't really care for the look or the feel of it. It seems to lose some of the sensitivity. I have only used it a few hours so I will save judgement. If not it will come off.
The palmguard and button cover are exactly what I was hoping for. Well worth the $20. Gone are the smudges and fingerprints which drive me nuts.
Now I am in the hunt for a skin or cover for the top of the Macbook.
