Paruline is my current on-the-go workstation, a ThinkPad T480. It is used and originally from a business stockage. I use it for different tasks while on the go/not at home, but it is mostly used for studies and writing for my university.
I made some minor tweaks, such as replacing the plastic trackpad with a glass trackpad, switched to a more powerful battery, extended it to 16GB of RAM, and underclocked the CPU.
It is powered by Fedora, a Linux distribution.
