Whether you can get away with a cheap laptop really depends on what you’re doing.
Like for someone who works in Photoshop/Illustrator/Sketch/Figma even a little will need a great screen and almost without exception you’re not going to be getting that in a $200 laptop. This admittedly can be worked around with a “cheap” $300 IPS external monitor, but at that point you’re spending more on the monitor than your laptop which feels upside-down. (I know this from experience — at one point I had to do PS work on a $500 Gateway laptop and it was miserable because a quarter of the document’s details weren’t even visible).
Or if you’re compiling code a lot, you’re going to want more oomph than a $200 laptop can provide, because otherwise you’re going to be twiddling your thumbs and getting distracted and breaking flow waiting for code to compile. For me this is particularly impactful, and any reduction in compile times is easily felt.
As for hinges, on even a number of “mid tier” laptops, they tend to get loose and wobbly over time. I’ve seen a number of IdeaPads owned by friends and family suffer this fate.
