In the title. I have a 11" 2011 MacBook Air (which I feel is one of my best consumer decisions to date, and isn't going anywhere) but I'm looking to purchase a cheap laptop that I can just run into the ground. It should be compatible with Linux/BSD out of the box. That means integrated graphics and solid network interface cards. What are my options?
Edit: Battery life is not an issue. I am tempted by a cheap desktop, but I hate the idea of having cables everywhere and a great big stinking tower under my desk.
System76 also makes amazing laptops that "just work" out of the box with Linux (most distros). They even have full support sine they sell with Ubuntu pre-installed.
Dell has a good track record for me as well, although I personally prefer the T series Thinkpads myself.
