Lenovo IdeaPad Slim 3i (15-inch Intel, Gen 11) is the pick for buyers who want a bigger screen and the option to upgrade. Lenovo's US listing for model 83RR003BUS shows an Intel Core 5 315 processor, 8GB of DDR5-5600 memory in a SODIMM slot, a 512GB PCIe Gen4 SSD and a 60Wh battery with Rapid Charge. The 15.3-inch 1920 x 1200 IPS touch display runs at 120Hz and 400 nits with 100% sRGB, the smoothest and one of the brightest panels on this list. A 1080p IR camera supports face sign-in, and Wi-Fi 6 and Bluetooth 5.3 handle connections. Lenovo says the chassis meets MIL-STD-810H durability standards. Because the memory is a SODIMM module rather than soldered, it can be upgraded later, unlike the Dell 14S. The drawback for this list is pricing: Lenovo's US store shows frequent discounts and the price did not load in a form our checker could confirm, so the price is marked pending. Check Lenovo's page for the current offer.
