Robert wants to buy a personal computer that is well built and runs Linux with a 17" screen. Leo says that most laptops top out at 15", but there are a few 17" models still available. Lenovo is one of the few manufacturers that ship laptops with Linux. Lenovo's P51 has a 15.6" screen. Lenovo's X1 Yoga has a great 15" model with an excellent keyboard. Some have OLED screens as well.
Leo also likes the System 76 Oryx laptop, which also runs Linux. They also will be coming out with their first internally designed laptop this summer.
