In this article we're going to talk about the lightest 15-inch laptop available as of the Fall of 2018, the Acer Swift 5 SF515-51. I'm highly skeptical around any device associated with the words "lightest" or "thinnest", but this one is actually a pretty solid product with some unique traits.
slim; compact and very light; beautiful; simple aesthetics; good quality IPS screen; but glossy; performs well with daily activities and runs cool; good battery life; competitive pricing
some design quirks; limited IO - no TB3 or card-reader; not one my favorite keyboards; rather poor speakers
