TUXEDO Computers is a German computer company manufacturing and selling notebooks, high-end gaming computers, and workstations powered by popular GNU/Linux distributions like Ubuntu, Debian, Fedora, Linux Mint, or OpenSuSE. The TUXEDO InfinityBook Pro 13 is one of their latest and finest ultrabooks running a custom Xubuntu OS that the company calls it TUXEDO Xubuntu. At first glance, TUXEDO InfinityBook Pro 13 looks great thanks to its ultrabook aluminum chassis. It’s outfitted with enough ports for everything you can fit in the system, but we’ll take a closer look at the hardware specs in the paragraphs below. Of course, the best part is that it comes pre-loaded with a Linux distro, so you won’t have to install one, but you can do that as well.
