[This review was collected as part of a promotion.] After 3 months I can say we've been overall very happy with our C940. Nice build quality, smooth track pad and keyboard, solid battery life, and the screen looks bright and has good viewing angles (much better than our old MacBook Air.) There are some helpful features built into the Lenovo Vantage dashboard that allow you to fine tune your performance and system behavior. Only gripes are the lack of Windows Hello on our unit, and no OLED screen available when we purchased ours. Overall great laptop and very glad we upgraded!
