Do not buy Lenovo laptops. The Yoga c740 I bought last July died mysteriously after a year. I am never buying another laptop computer. The Yoga cost me $900, I never went on the internet with it, only ran MS Office on it, and the power supply on the motherboard fried out of nowhere. People...I grew up with computers, and a laptop lasting only a year is UNACCEPTABLE. Consumers need to start demanding better quality computers, and the way to do it is to NOT buy ones of poor quality. I ended up smashing my Yoga with a hammer and throwing it away, but I wish I could have slapped a Lenovo executive in the face with it first. To Lenovo: if you don't improve quality, you will be out of business in a few years.
