Ask Slashdot: GNU/Linux Laptops?
"I'm an OS X user looking to switch to a Linux laptop. I like the Unix/BSD aspect of OS X. Simple things like when I close the lid the laptop goes to sleep, the sound card works out of the box, long battery life, minimum cooling fan noise, and a comprehensive but relatively straightforward backup system and 'AppleCare' package are important to me. What all-inclusive model of laptop and distro would you recommend?"
He didn't mention it, but I am presuming that working Wifi should be on that list too.
Perhaps he does not want the comparatively walled (though curated?) garden of a mac. I agree, though, almost all of the "just works" aspects that he want sounds like it would fit a macbook.
