From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have a T480 and the battery will last me 2 days on a charge for my typical use. Since it has two batteries, I can swap the external one without having to plug in or shut down. There are lots of parts available and you can find used or refurbished laptops at a reasonable price.
The downside with the T480 is a lack of PCIe lanes. The thunderbolt only has 2 lanes, which is not so good for an external GPU. The NVMe SSD is also only 2 lanes, but I still get around 1.5GB/s, which is plenty fast for me.
