I threw up my hands in 2001 and went from WinXP to Apple. However, I had the second Windows smartphone (back then, they were "PDA phones") because if I was going to carry around a chunk of shit like that, it better do more than make calls. It didn't do quite enough - I still have a Gen1 iPod and it still fires up and plays music.
But I threw up my hands in 2015 and went Android and, professionally, back to Windows. Android? Windows? They're stupid and capricious. But Apple has become mean. They are actively harming their existing userbase in pursuit of the new user experience. They're training consumers that if you want reliability you need to buy a thousand dollar phone every year, pay $15 a month to listen to your music, and keep all your photos and documents on their servers.
They have become a vicious and greedy organization. Android? Windows? Clumsy, flat-footed and often completely wrong-headed. But they act out of stupidity, not spite. Apple used to know better. It makes it infinitely worse.
