If portability and battery life are top priorities, the Dell Inspiron 14 7425 stands out with its smaller, lighter build and longer battery life, also offering a higher resolution screen and the flexibility of a 2-in-1 design as it can double as a tablet. However, if you're looking for a larger display, more storage, and a potentially more powerful processor for intensive tasks, the Dell Inspiron 15 3511 can deliver that at a lower price point. It lacks the tablet mode and has a shorter battery life, which can be important if you're often on the move. Give Feedback

Jared Newman | December 2021
"Overall, this Dell Inspiron 14 2-in-1 offers a lot to like, especially at its oft-discounted price of $800. It’s a sturdy laptop with strong performance, a convertible touchscreen, loud speakers, and a convenient fingerprint reader. But the trade-offs you’ll make in pursuit of that lower price—most notably the dim display and stiff trackpad—might just keep you from outright loving it."

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."
