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."

Matt Elliott | January 2023
"Despite its good looks, stellar webcam and comfortable keyboard, the Envy x360 15 is hard to recommend because of its dim, 16:9 display. If the display isn't an issue for you, just be sure to wait for a good sale price. Otherwise, a more modern two-in-one with a 16:10 display such as the Dell Inspiron 16 2-in-1 or Lenovo Yoga 7i 16 provides a larger workspace without adding much to the size and weight of the system."
