Back to obscurity
The googly Motos had a single selling point for me - you could maintain them for ages after that with Cyanogen (besides their own software updates).
Cyanogen is hit and miss (9 was excellent 10-10.1 so so, 10.2 unmitigated disaster, 11 excellent again). However, when it hits - f.e. with 11 (4.4 kitkat) on my Sony Xperia Arc, it provides your phone with years of life after the manufacturer has stopped supporting it.
This was the norm with Googly Moto - they are all on Cyanogen. The norm with Lenovo is the opposite - no support. So the moment they switch to the next model you can kiss your updated goodbye and congratulate yourself with another paperweight.
