Which doesn't mean parent is wrong. You can do any work on non-ideal equipment and be happy with it for various reasons. When I saw what one of my ex was using (bio chemist growing various stuff and testing treatments to rare sickle cell anemia that pharma didn't care about due to low patient count), it was very subpar and inefficient but she was happy with it and got results nevertheless eventually. Some of her work I could make more efficient by 10x, some by 50x maybe, but ie she as hardcore unix person just plainly refused to use MS Excel and all its statistics power, to pick a random example (there were quite a few). Not saying this is your case of course, but oh boy do small screens, limited browsers, limited power and storage speed etc. do have negative effect on work itself, mental flow, staying focused etc. There is a reason not only we IT guys want powerful machines and massive screens, it ain't just chasing shiny higher numbers.
