I have a crack on the bottom right, from the bezel down in a south/east direction.
I have had that crack since, let me think, spring of 2011 or so. I just stuck a matte black skin on it. Out of sight, out of mind. Never had any issues with it.
I was still under warranty at the time, but I just didn't want to go to all that trouble loading another unit. I had to go through 4 of the K3 when they first came out in August 2010.
But I have to say that conversation comes across rude. Not from the CS though. I mean I get you want something, but the tone, oy the tone. For something that is way out of warranty and they still offer something. Try that with another company, good luck
But then I always cringe when folks present themself of being something special for various reason. As in, boards, influence, etc. These CS guys go through a script. I doubt they care about any of that.
