I've been using ThinkPad E14 (AMD Ryzen 7, 16GB RAM, 512 SSD) - very happy with it. No problems with performance, battery, etc. at all. The new Dell XPS 13/14/16 is also good. Just get one with Windows and wipe it clean when installing Linux.

In fact, I was going to buy a $4K M4 MacBook before I saw Omarchy and decided to give it a try with a new $730 ThinkPad. Exceeded all my expectations. Omarchy literally saved me thousands of dollars.
