Henry T. Casey | April 2018
"The Dell Latitude 7490's got the speed you need (and then some), a keyboard that's comfortable enough for writing all day long and a battery that supports a full 8-hour workday. If only the display were brighter and it managed heat better. If you need every minute of battery life you can get, the extended-battery version of the Lenovo ThinkPad T480 lasts 8 hours longer than the Latitude 7490, but its display is much less colorful."

Marvin Gollor | February 2023
"The low-priced IdeaPad 3 14 delivers on core functionality. Lenovo's IdeaPad 3 14 meets all the basic requirements for an inexpensive office laptop. The matte IPS display is bright enough, the performance is high for the class, and the input devices are rock solid. In addition, the mostly quiet operation including the useful performance modes, cool surface temperatures, easy maintainability as well as expandable working and mass storage all contribute to the IdeaPad 3 14's value proposition."
