"The laptop does not sleep in Linux" is not a compelling reason to hate a manufacturer without a lot more details, but I always hear it as some catch-phrase when people talk about Linux/Laptop compatibility. linux isn't linux isn't linux. distribution and wm/de matter a lot with regards to power management, and many distributions/DEs have strong opinions about defaults in many different directions. I wouldn't expect a lot of laptop specific tweaks in a performance or desktop-flavored distribution, just as I wouldn't expect a high performance/risk file-system or IO scheduler on a user-friendly consumer-centric laptop-oriented distribution -- thus I think it's an unfair assessment when someone judges the other end of the field from the wrong side. All that said, I own a current gen XPS15, i've ran just about every major flavor of OS on the thing. The compatibility is exactly what i'd expect out of a generic Intel 'ultrabook', ubiquitous.
