I have had my macbook pro 13 for about 4 months. A month ago I notices a small stain on the trackpad, now its has spread around the edges of the trackpad. They really do not interfere with functionality but its an ugly stain and I did not pay my money to have a stain on the trackpad. The stain seams to be under the glass of the trackpad. I just wanted to ask if any one had any similar issues and if I took my macbook to the store would they replace the trackpad or replace the macbook entirely? Here are some pictures of the stain.
