I find it annoying that the community pretends otherwise.
Someone goes on a forum with their laptop with an nvidia card and a wifi card no one's ever heard of, and more likely than not he'll be told it'll be easy to get linux running on it.
Hell, I was wrong. It's not just that a lot of linux users don't know much about windows, they also don't seem to know about the issues people can face with linux on some less or non-compatible hardware.
You can be a linux fan and admit that companies like Nvidia, Realtek or HP often don't give much of a shit about linux, but some pretend otherwise.
