The killer for Apple is that once I switch to a Windows machine, I no longer have a great reason to stay with iPhone, either. Hell, that Pixel looks mighty nice and there's no big difference beyond waterproofing between that and iPhone 7 once the ecosystem is no longer a selling point. I might be ditching Apple for Microsoft, which would then be quickly followed by Google's Pixel. The Google services (photos, music, etc) are 10-times better than Apple's offering, but staying in a single ecosystem has prevented me from switching. Looks like that won't be true much longer.
