Could it be because you spent $500 on it for the purpose of reading books, and your mind won't let you think negative thoughts about the experience?
I had a pair of pants like this. They were the wrong size, uncomfortable, and ugly. But I wore them anyway because it was too late to return them, and I spent $75 on them that I could never get back. So I just learned to like them, even though they were fundamentally flawed.
