Good dev machine with a bit more RAM
My main use being dev (scientific computing and occasionally games) under Linux, my main criteria were to have a maximum of CPU cores, with a good multicore frequency (so we avoid the "U" series), if possible a maximum of RAM and to avoid NVidia GPUs (the NVidia driver under Linux being... characterful).
For this use, this machine seemed to me to be the best option available at the moment, with a RAM boost that was a bit low for dev (the machine being rather targeted at gamer customers, who are less greedy at this level).
It is indeed very good in practice: quite compact, good autonomy, nice screen, perfectly silent when not consuming resources, and turbo CPU at 4.2 GHz that can be held for a long time even with several cores.
My only complaint is the keyboard, which has made some unfortunate compromises in terms of compactness: the key has been moved to a very unusual location, the windows key has been kept on the left side only (I would have preferred the right side), the odd mix of enter/* which takes some getting used to, and the start/end keys which need to be accessed via the fn modifier.
