Happy to see a Zen 4 version of the Z13 being announced - we need more AMD powered ultraportables!
I have the Gen1 Z13 with a Zen 3+ CPU and it looks great - no more boring boxy black plastic, its all brushed aluminum - think MacBook meets ThinkPad. I run Fedora Linux on it and everything worked out of the box, including WiFi, standby, all the Fn keys etc. It's also one of the few ultraportables which can be purchased with 32GB DDR5 RAM (which is handy for running VMs and containers). I can even update the BIOS and firmware via fwupd, so there's no need to boot into Windows. Gaming on it is also pretty decent thanks to the RDNA2 graphics. Also, I get an all day battery life on Fedora (when I'm not gaming). I finally found the perfect Linux laptop and I'm so happy.
