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."

"The ThinkPad X1 Titanium is a showcase of what Lenovo thinks business computing will look like in the near future. People want thinner, lighter laptops with high-quality screens and enough computing power to get their work done. The X1 Titanium achieves these goals with some controversial but innovative design choices, including a redesigned keyboard and a pared-down port selection."
