I have one laptop from Asus from their price/value segment (R301LA) and I can't say that everything runs out of the box: - wmi keys (i.e. brightness regulation) - touchpad (Elantech) doesn't work after suspend (it disappears from /sys/ so it's pretty damn undetectable) - it doesn't always suspend after closing the lid Sure, You can live with that (and with mouse attached), but when you buy a laptop from company that makes money on Linux (Android devices, Chromebooks) you expect better treatment.

Ubuntu --> Debian testing --> Arch --> Gentoo (desktop) + CentOS (VPS) + Ubuntu (desktop and laptop).
