Kaby Lake Upgrade. A powerful processor, IPS display and quick SSD: these are the fundamental building blocks for a good office computer, and the Inspiron provides them all. A backlit keyboard and a good battery life build on that foundation, and the built-in touchscreen can be operated with a stylus. The whole package costs just under 800 Euros (~$850).

Thanks for review, are you sure in your statement about the weight?
It sounds very weird for 15" laptop even if it's 2 in 1. The weight on the Dell's site is 2.3 kg which is 500 g difference.
You should just omit that active stylus support when it is not pressure sensitive. It's not an official Dell stylus nor it was mentioned by them in the first place. This is like saying every capacitative touch screen support passive stylus.
the weight mentioned is incorrect, its somewhere around 2.2 kg
and i have used it .... the convertible feature is really not that helpful but yes the touch features helps a lot.... getting around 5 hrs easy backup
