"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."
