As you said, pmOS and Leste are more mutualistic than competitors so I think that's good. Also, I'm very excited with Leste and looking forward to trying it on my Pro1, but on the other hand I also see pmOS as a real good OS to run on a Pro1. With my use of Debian in LXC on top of SFOS, I really grew a dependence for desktop WMs, and pmOS allows using many WM or DE.
