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. Many of its slightly higher-end rivals have to be on sale (and frequently are) to match it on price, but the Inspiron 15 (3525) is outclassed even by some similarly priced options, making it a difficult recommendation."

Monica Chin | July 2021
"The best thing about the ThinkBook 13S is that it’s a good deal. Business buyers looking for ThinkPad-level performance and software without ThinkPad pricing will probably find the ThinkBook a solid option. While nothing about it is really spectacular, it’s certainly unusual to see the ThinkBook’s screen resolution at a sub-$1,000 price, and its performance will be more than adequate for most office tasks. The generous port selection, 16:10 aspect ratio, physical webcam shutter, and clear audio are certainly icing on the cake."
