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."

"Lenovo’s IdeaPad Pro 5i represents an impressive opening salvo for Meteor Lake in the ultraportable space against familiar foes from AMD and Apple. Not only does the Core Ultra 5 125H processor provide good performance across the board, but battery life remains a strong point against the Acer Swift Edge 16 with its AMD Ryzen 7 7840U processor. It can’t quite match the endurance of the 15-inch MacBook Pro, but the gap is shrinking."
