SO when then?
My Nexus 5 broke in the summer (not sure, but think software not hardware), so I schelped off to a shop to get something else. Found out they had nothing recent in stock (small town in NW Spain), so got what seemed to the least worst solution on offer - an LG G2. It's still today on 4.4.2 of Android and I am very happy I just got back a Nexus 5 in working order. I am not even happy to give it to someone else... never mind the drawer full of half-dead/dying/dead androids I have already....
I understand why Google did what they did to get into the market, but they ended up with a Microsoft situation MINUS control. If they don't bring out another sensible Nexus I will have to go to Apple (and believe me that is really not something I want to do) or be really dumb and take a Ubuntu phone (big fan of desktop, but first generation anything is sh1t).
So, Google, please fix the downstream process with partners...
