This article lists the best Linux laptops that come with the open-source operating system preinstalled by the manufacturer.
Linux is an open-source operating system that you can install yourself on nearly any computer. So, why would you want to buy a specific Linux laptop instead?
Many laptops advertised as Linux devices normally come with Windows installed but have been tested and certified for some kind of Linux flavor. However, the devices in this list are purpose built with Linux in mind. This means that they will often run faster, smoother, and integrate better with the hardware than if you were to install Linux yourself.
There's one downside to buying from small manufacturers: most purpose-built Linux laptops cost slightly more than those with Windows. Part of the reason Linux devices tend to cost more is that boutique manufacturers produce small numbers of product, which makes per-device costs more expensive. The exception to this rule is Dell, which actually reduces prices when you choose Linux over Windows.
