I have been with Windows Phone since day one (hello, HTC Surround). I have been through days of no copy/paste and multitasking and situations like apps more than 25 mb would refuse to download with my data connection. Those were the days. I have switched to android (Galaxy S3 and S4) and recently to iOS. The app selection on both are fantastic. However, I got bored after a few months.
Now I'm back with a Lumia 930 and genuinely felt at home. It's the simple things that makes me stay. The way my start screen feels alive, the awe my friends have when they see my tiles flip and show info right there and then. The smoothness of the animations and the way my son giggles when he asks silly questions to Cortana. It feels right at home.
If you adopted WP when 8.0 was launched and say there is no progress. Come on, I have been here since WP7 days and I can say the platform has come a long way. Sure, I admit it's a bit slow when we talk about getting games and apps. Or the usual rant that apps on iOS and android are much better which admittedly is true. Windows phone gets the job done, I guess that is what really matters.
So you can leave and trash windows phone all you want. But there are a people like me who will stay. Maybe because we see it the way it's supposed to be seen--not iOS, not Android, but Windows Phone.
