Actually, yes. Given my computer is always on display on a desk or table in my home, I consider it to be a piece of furniture. Therefore aesthetics are as much a consideration as they are for anything else I buy for for my home.
Just like people buy cars/homes/clothes/cellphones just because of how they look.
I'd argue they should look at the overall "package" when purchasing, but if looks are important to someone that's absolutely fine, and there is nothing wrong with valuing looks.
That case could do double duty as an axe in a pinch. It's incredibly solid. I really wished the hardware was more standard there is no way I'm going to be using OS/X.
