Well there’s always the option to buy something like a Samsung Galaxy Book3 360. It’s a laptop that comes with an AMOLED touchscreen, a 360° hinge and the S-Pen. You can put a GNU/Linux distribution on it and enjoy free/libre and open-source software with a tablet-like user experience while keeping your integrated keyboard and touchpad (it’s the best of both worlds!), and the S-Pen is amazing and works on Linux because it uses standardised Wacom protocols. They’re not inexpensive though.
