I'll add I've witnessed bad mechanical design from Lenovo. A friend bought a $1000 laptop (U330 touch) from them and a piece of plastic holding a hinge broke. When I looked at it, it was clear that the part could have been 10 times (yes, 10) thicker without adding much weight (about a gram I guess) and probably zero cost. I find this mistake nearly unacceptable but the evil part comes when you ask for warranty and they tell you that you must have done something wrong, why would a hinge break otherwise? And you accepted the warranty terms, so its their right to say so. Quality control also was an issue as the laptop first came with a malfunctioning keyboard and a non operating touch screen. So yeah, now is not a good time to buy anything from Lenovo.
