I partly agree with your opinion when it comes to the ASUS laptop. My laptop in question isn't a good example of a trustworthy one. However, I have still another ASUS laptop (17"), Windows 7 from 2012, so will not go online but still perfectly working to watch a movie when too lazy to choose for another device. The only thing, the battery has to be replaced, but who cares, in this country with electric power supply guaranteed 24/7 no need (joke). My best buy is also a MacBook from 2014, ever since up till now not even one minor problem. Nevertheless, I am not a real Apple fan coz with 3 successive iPhones of which the last 2, I had more problems than I ever had with Android phones of various brands. For me iPhone is a non-goer for always. For the bottom price of an iPhone I can buy 2 or 3 or 4 Android phones and my experience all working even after 5 years. What can happen is that the OS on a specific Android phone is no longer supported and thus not safe and accepted for online banking and more. The choice between a laptop or desktop is rather personal. As for myself I will not decide to go for a desktop again in spite of more advantages.
Yes of course that choice is personal. For me however, when I'm home I have no need to move around while on the computer, so I still favour a desktop setup. I replaced my then 10 year old desktop 3 years ago (Lenovo Legion T5) , and the monitor two years ago. I have a 32" Samsung monitor now, nice and big, so I don't even bother to watch videos, films or live tv streams on the television anymore. I do have a small lightweight laptop (Toshiba 13.3" Dynabook) for when travelling, but often don't even bother to bring it.
