It's hard to predict the Linux version as more effort is directed toward the MS Enterprise version. The DEV channel runs weeks ahead of BETA of course and I've had no problems with it, and they have committed to scheduled weekly updates. It has been very stable on Linux Lite for me thus far but there are a few shortcomings with video and such, mostly having to do with Google and media applications. Google and MS are in a telemetry war. I'll get a list together of known issues. Generally it is ready, but I expect hiccups with Google over security.
