What made the earlier Nexii (4, 5, 7) a success was, in no small part, the sticker price, way lower than Apple and other were selling similar products. With these, you were getting great devices (with shortcomings for sure, but not deal breakers) for a bargain price. You could get a nexus 7 for less than 200USD. That to me was the power of Nexus, to the point where I would easily overlook hardware/software issues.
Now that those are gone for good, we are left with the Nexus 6 and 9. They are priced on the high end (really high end). At that point, it's only fair to compare it to the competition on equal grounds. The Nexus 9 is the forgotten child, still not updated to 5.1, and with performance that is not up to a iPad Air 2, nor its build quality. The Nexus 6 is monstruosly big (if you loke those sorts of things) but the performance is OK at best. Apple used to be blamed (correctly) for sticking to small screen size, when everybody else had plenty of choice. Now you can get bigger or smaller phones from them, but not for Google.
I loveD Google's products, but I am no fanboi. With the passing of the Nexus 7, I can't say I feel the same way any more.
