Yes, LG is releasing an ultra light weight laptop which claims to be the lightest laptop in 15 inch category. The weight of this laptop is less than 1kg, to be exact 980g. The laptop is said to be very good for gamers and creative professionals. For gaming it supports AMD's FreeSync tech which ensures smooth performance. Its IPS display with 21:9 aspect ratio has a magnificent resolution of 3440x1440.
I think this weightless beast with 4k display could be a winner as it is an attractive model with high portability.
