Sxmo: impressive demo of an X environment for Linux-based Smartphones

Just saw this demo of Sxmo (Simple X mobile), a lightweight X environment for Linux smartphones, showcased somewhere in the first AlpineConf this year.

It's pretty impressive what you can do with a ported dwm inside the smartphone screen and environment, where you depend on gestures and key clicks to make stuff happen. I'm still generally against mobile phones, but a fully-free Linux handheld would still pass on my book. If only they became more accessible (in terms of ease of buying, not exactly price)...

Do you own a Linux mobile device (phone or otherwise)? How usable is it, enough to daily drive? Let me know on Mastodon!
