Considering your needs, the Dell Inspiron 16 5635 is a robust option with an AMD Ryzen processor providing ample computing power for general use, and its larger screen with higher resolution is beneficial for tasks that require more screen space and clarity, like photo editing or multitasking with multiple windows. However, it is heavier and bulkier, which may not be ideal if portability is a top priority for you. On the other hand, the Lenovo IdeaPad Slim 7i, while having a smaller and lower-resolution screen, is significantly lighter, making it easier to carry around, and it also boasts an Intel processor with integrated graphics that can handle everyday tasks effectively. If long battery life is important, the Lenovo seems to offer slightly better performance, but if you're looking for silent operation, the Dell stands out. Choose the Dell if performance and screen size matter the most, or the Lenovo if portability and battery life are your main concerns. Give Feedback

Derek Sullivan | January 2023
"Compared to the previous year’s Inspiron, Dell upgraded the screen aspect ratio on this generation, but also transitioned to a more minimalistic centered keyboard flanked by up-firing speakers. The 16-inch screen is huge plus and I really appreciate the extra real estate without sacrificing the footprint much. This year’s model is a little larger than last, though, as the former model was already very small for a 15 incher."

"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."
