Should My Wife and I Replace Our Sofa?

Here is another rare deviation from the no-nonsense tenor of this blog.

In an attempt to make me seem too unmaterialistic, my wife, on the radio, made fun of me for not wanting to replace our sofa. She suggested I take a picture of the sofa and she take a picture of the best evidence for replacing it and see if the readers of the blog have an opinion.  Those photos are below.

First, here are some facts to help guide your decision:

• The stained area is roughly two square inches. 
• We have tried to remove that stain and it can't be removed.
• Per the picture of the sofa, no one notices the stain unless they're on their hands and knees. 
• There are a few other "not-quite stains," barely visible and not visible in this photo. 
• We can afford to buy another sofa. My objection only is that the current sofa is as attractive as any we'd buy, is very comfortable, the perfect size, and it and looks fine. Per the picture, I believe a reasonable person would not consider the sofa anywhere near stained enough to justify spending the time and money to try to find a new one that looks at least as good, is the right size and style.

So what do you think? Should I hold my ground or give in? I'm really quite sure I'll end up giving in. Such is the way that such matters typically end.
