I've never known any kind of electronic device to not follow the rule of "you get what you pay for." If you want it to work practically forever, go with the expensive one.
I worked as an it business analyst for a larger multinational for a hot minute. Lenovo laptops were beastly and rarely broke. When 10 000 employees are all using t series laptops for years, with few breaking down, it made me appreciate your comment quite a bit.
I'm not trying to plug lenovo. There's very little difference between lenovo and dell at the enterprise level. Those are the ones I have experience with and so I'll comment on those. Just buy actual business laptops. Especially if you're not gaming
And if you are gaming I highly recommend avoiding anything labeled as being for gaming or gamers. A lot of that stuff is just cheap shit they want to sell for more and the fanciest thing about them is that they put RGB lights in it. Gaming chairs are a great example; you can often find the same exact chairs for hundreds of dollars cheaper by getting them as an office chair. They just might not come in super bright colors or have an e-sport team's logo on them.
