"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."

"Lenovo’s IdeaPad Pro 5i represents an impressive opening salvo for Meteor Lake in the ultraportable space against familiar foes from AMD and Apple. Not only does the Core Ultra 5 125H processor provide good performance across the board, but battery life remains a strong point against the Acer Swift Edge 16 with its AMD Ryzen 7 7840U processor. It can’t quite match the endurance of the 15-inch MacBook Pro, but the gap is shrinking."
