Until recently, both Purism Librem 13 and Librem 15 laptops were available only as made-to-order, which means that those who wanted to purchase either model would have to order it first and then wait a few months until the device arrived. And now, the company finally managed to scale the production to hold inventory of the laptops. Powered by Intel Core i5 (for the Librem 13 model) and Intel Core i7 (for the Librem 15 model), both laptops are powered by Purism PureOS, which is a derivative of Debian GNU/Linux. However, users can have the laptops shipped with the more advanced Qubes OS security-oriented GNU/Linux operating system.
