To play Devil's Advocate for just a second... (and to be clear, I've owned every iPhone release and used an iPhone as my daily driver for all but about 9-10 months since the original iPhone. Most of my other tech is also from Apple)
1). Fair point, especially if you keep your phones for more than 2 years. Many don't and I'd wager most on these forums don't. Also, you are guaranteed Security Updates for 3 years, I believe. If you are hoping for more on the Android side, you won't find it anywhere else.
2). Have you ever tried running a current version of iOS on anything older than 2 year old hardware? It's often just as bad.
3). See this arguement a lot but its funny how the opposite is never brought up. Who provides the most widely used email service and how long has it been around? Same question regarding maps applications. And internet searches? Who's OS is now on more than 50% of the computers in Education in the US? Hint---all from the same company. Apple has some current products 'languishing' on the vine (not dead yet)--hope you haven't been holding your breath for an updated Mac Mini or Mac Pro.
Point is, every company has some failures (even the almighty Apple
--how's MobileMe, Ping, and the Apple HiFi working out for you) and for a company like Google who tries a lot more than just about everyone else, there are going to be some misses. But it's had some of the internet age's biggest hits as well.
The Pixel doesn't offer the pinnacle of mobile hardware and is certainly far from a sure fire homerun but IMO, it's a huge step forward for Android. I'm expecting my XL to be delivered next week and it's the most excited I've been for a new piece of tech in quite a while.
