I don't think it is bizarre that Linux users reject Linux laptops.
I do it myself. Why would I want to purchase a laptop that has worse screen resolution, no SSD and no customization options?
There are Linux users who are cheap and would want such a low-end laptop. I am not one of them. I want the extras.
So far the only laptops I really like are Thinkpads, Samsung Series 9, and Apples.
As for existing Linux users buying Linux preloaded...why would they? They've obviously already managed to install Linux themselves or they wouldn't be Linux users. Doing a fresh OS install holds no fear for them.
