My IT department recommends a Dell Inspiron 14 5000 or a Dell Inspiron 2-in-1 7000. However, security and FOSS are very important to me. I want a laptop with some form of open firmware—such as coreboot—but I also strongly prefer AMD to Intel. I am a freshman going into college to study CS.
Remember that you can buy a laptop without Windows, save some bucks, and install it linux. But you probably are gonna need it.
