I don't make apps. I buy them. My ability to buy them is predicated on other people writing them to target WP7. Microsoft's messaging excludes WP7. I am well aware that you can target WP7 and WP8 simultaneously; I am also aware that Microsoft doesn't really give a shit if anyone actually does and that it is an absolutely insane proposition to expect greenfield development to actually target WP7 today--because why would it? I sure wouldn't, because the WP7 market is tiny! But it's Microsoft's job to take care of its early adopters who trusted them, and their messaging indicates no desire to really do that. OS releases and app releases are two different things, and Microsoft is falling down on the latter in a way that means I will simply not go there.

I want my phone to have the literal newest-and-best for at least two years and I don't want the platform setting a direction in which I am not explicitly included as a first-class citizen. Which Microsoft isn't doing. And, sure, you're right that Apple doesn't do that either! Great! I use my Android phones as daily drivers and the Nexus devices do exactly that. Why should anyone do differently?
