My experience with the LG Gram (early 15" and recent 14" 2-in-1) is really nice keyboards, probably the best in consumer class next to HP Spectres and Microsoft Surface. Battery life, upgradeability, I/O and weight are also currently better than any other flagships from Lenovo, HP, Dell and Apple, coming at 1kg with 72Wh batteries, socketed DDR4, and 2 NVMe slots which is unheard of. On top of that the Grams are crazy durable because of their unique unibody carbon-magnesium alloy chassis design.
Unfortunately poor speakers, webcam and microphone - some of the worst on any laptop I've used as LG haven't upgraded them in years - and poor cooling system combined with only average screen is not worth the premium price, especially as you begin to spec-up the laptop. Recent i5 base model with TB3 is maybe okay but not over $2k for i7.
Some other drawbacks include no Fn function lock, very uneven keyboard backlight with only 2 levels, and only 1 USB-C port on 14" and lower models. Also all existing 5 models from 13-17" use outdated plastic display bezel (or B-cover) implementation, which results in unavoidable backlight bleed and the screen being the weakest point on all the laptops. The rest of the chassis feels surprisingly solid, except for the display which is a shame.
If LG acknowledges and resolves 3 major issues - the cooling, audio and display - going forward and decides to offer AMD Ryzen SKUs, they will be worth considering but as of now, the rest of the competition at this price is simply too ahead on all 3 fronts.
