Here is a relevant tip:
Instead of buying consumer-grade new laptops, buy used top-of-the-line corporate (or gamer) -grade laptops that are 2-4 years old which cost about a fraction of their original prices.
You'd get acceptable performance, larger memory capacity, and usually a wide array of spare-part options because these units are designed to be parts-swappable, unlike consumer grade laptops that has "planned obsolescence."
