"If laptops were food, then the Dell Inspiron 14 5420 is arguably a Big Mac. There are cheaper and more expensive options, but this arguably represents the baseline of quality and value in the world of mobile computing… something that’s underlined by the attractive $1,279 price tag."

"Not only is the Aero 17 a very good laptop for gamers but also for content creators. With the upgrade to the Intel Core i9-11980HK, Gigabyte particularly improved the system performance. In addition, the hardware package is rounded by the extremely fast SSD and 32 GB of working memory in dual-channel mode. Compared to the predecessor, the battery life is reduced only moderately, and the 4K display also basically keeps its good qualities."
