PCMag
Mark Knapp | January 2023
"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Plus, those alternatives are much more enjoyable after work."

"In the past, the XPS 13 was a hands-down contender for the best laptop on the market. But the Apple-silicon MacBook has since barrelled onto the scene, and it wipes the floor with most of the ultraportable Windows laptops that cross my desk on a daily basis. This XPS is no exception. Compared to the M2 MacBook Air, battery life is worse."
