I owned only Nexii from 2011 on and I'm not even sure Google wants to update those thoroughly. They sacked 4.2 for Nexus S, 4.4 for Galaxy Nexus although they can run it (and they did with custom ROMs) just fine. Last straw was the Lollipop update for the Nexus 5, where it turned out a perfectly working device into a nightmare with memory leaks, mobile radio drains and camera freezes, where a daily reboot was actually mandatory. Their bug report tracker is full of complaints, yet they didn't do anything and are casually talking about M. Sorry, I don't have to wait a year, then pray if my current device is going to be supported, or just cave in and get a new device the new Android revision will enter the market with. So until customer experience becomes a priority, I'm not investing a single cent or a second of my time in Android.
