maybe calling it e-waste is not really well thought through. Because as someone said, most will not be upgrading from 9A, but from older ones.
Nevertheless, and it's not just google at blame here, releasing something just so you can say it's "new", when it is in fact nothing new worthy of mention, is despicable. But we consumers are to blame.
Google is an awful hw designer, and they are a-holes for keeping basic functionality down, just because they can't innovate, so they have to keep some strategic reserve. Like, maybe next year (or the year after that?) they increase battery to 6000 (when competition will already be at 8000 or 10000) and call it an upgrade.
