I love how people use the stupid "I love people who..." line to make their opinion seem more valid, when it's not.
The quality on the Y580 is hands down on a whole order of higher quality then my wife's 17r SE. The keyboard on the Y580 is the best laptop keyboard I've ever used, the screen is magnificent, and it feels rock solid to hold.
Every Lenovo I've purchased or recommended has had 1 thing in common, and that is quality.
