Eagerly awaited and so far living up to expectations. This is a cool piece of kit, and it is handling multiple programs at the same time with ease. I tried out using the latest version of Sonic Pi 4.5 for Raspberry Pi Bookworm, together with a Libre Office Slide show, and OBS recording the screen plus audio and it didn't have any problems with this. The bluetooth performance with external speakers is good and easy to set up. I've mainly used it with Wayland, but occasionally switched back to X11. Requires a restart but otherwise OK. Also I find Pipewire works pretty well with audio midi and video routing.
