PCMag

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"The numbers don’t lie — the HP Spectre x360 14 (2024) is a star, and a hell of a one at that. From performance to battery life, this machine is a dream. But why didn’t I give it a perfect score? Well, I wish the display performed better and that there were more ports to go around. If you’re itching for someone a little cheaper that offers a brighter display and significantly more battery life, I can only recommend the MacBook Pro 14 as a suitable substitute. Otherwise, the HP Spectre x360 14 (2024) is the perfect choice for those who want a reliable premium laptop."
