Finally got my #nokian900 on Friday. Tested #maemoleste and #postmarketos. The latter is already quite usable (if you can ignore that the recommended option currently is XFCE, which is not really touch-friendly).
So I decided to turn back to Fremantle for now (which still gets fixes from CSSU btw) and keep an eye on the development of both PMOS and ML. Will use it as a rock solid rockbox player for the time being. This thing even reads my big sdcard :) #nerdheaven
