History repeats itself again!
"A cut-down experience on '10'..."
Remember the days when Microsoft was transitioning from WP7 to WP8? At first, they were coy about the possibility of upgrading the OS on older devices. Then they hastily promised that no one would be left out on the 'Windows Phone experience' and every WP7 device would get upgraded too.
The upgrade turned out to be WP 7.8, a watered down experience, to put it kindly. OEMs got burnt, eager fans got burnt, said 'never again' and switched to Android or Apple.
This is why Microsoft will never dominate mobile... it has a penchant to shoot itself in the foot.
