Screen, Build Quality, Weight, Size great bang for the buck closest i have found to my old mac book air which I loved but i had to have a windows machine sorry mac.

Ability to add more Ram would be nice improvement, There are two USBC ports but both are on the same side of computer would be better if had one on each side. Audio could be a little louder.

I had the previous model and it was just OK. Fortunately for me I bought the full Memory Express warranty. I am not one for usually buying extended warranty's nor am i one for writing reviews but boy am I glad i bought the full memory express extended warranty because twice since i bought my last computer i had issues that were covered under that that extended warranty. The first was my touch pad locked up as a small bit of foreign material (maybe a crumb, don't eat near your computer) got lodged under the pad as there's a small gap between the pad and the body of the lap top (who new). Memory express service performed the repair under the warranty and i was up and running a few days latter. The second time was much more serious my machine stopped working as i had a problem with the USB C charging ports which meant i could not charge my machine. and this problem was unrepairable. Again fortunately for me i had the extended warranty and memory express put me into the new ASUS machine at no cost to me other than backing up my data from the old machine which was a small charge i could have avoided if i had my own back up. The machine is of a higher spec than the old one the only thing is it is not foldable like the old one was. For me that is not an issue at all as the folding was a cool feature it turned out to be something i never really used. This unit is much improved. The camera used to be in a flip up key in the middle of the function keys which was terrible as the angle of view was right up your nose. So far i am very happy with this new ASUS machine for build quality its the closest thing i have found to my old MacBook air which was a pc of engineering marvel but this ASUS seems close so far and the screen is amazing. So, if you want a small light portable PC i would say go for it. I have only had this one a week or so but so far so good.
