How the Dell Inspiron 14 7425 and the Lenovo Legion Slim 5 compare to other laptops
"Overall, this Dell Inspiron 14 2-in-1 offers a lot to like, especially at its oft-discounted price of $800. It’s a sturdy laptop with strong performance, a convertible touchscreen, loud speakers, and a convenient fingerprint reader. But the trade-offs you’ll make in pursuit of that lower price—most notably the dim display and stiff trackpad—might just keep you from outright loving it."
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
