I'll be patient and wait for a stable version.Maybe I should clarify - the graphics/display drivers are binary blobs, targeted at an old Linux kernel (still used) and old Android versions (long surpassed). No amount of 'improved stability' can fix...
Have the 15.1 builds ended? 16.0 must have had enough time to become a familiar entity I suppose.
You'll almost definitely want to max out the CPU to 1.5GHz, as the experience would be painful otherwise.
