Yeah I have the Libre Colour and it’s great! The pen feels good, it lets you do what you want with it (eg. using Calibre to strip the DRM off your books and loading them via USB, installing KOReader etc.) and it works well with Libby for getting eBooks from the library (at least in Canada.)
I actually didn’t know you could nest Virtual Desktops within activities, so that was nice. Now I can make my setup even more absurdly complicated for anyone who’s not me to use lol.
