I have been using Windows Mobile/Phone since 6.5 with a brief Android detour and an Apple workphone. Like most of you I have been a WP advocate among friends and family, but i am reaching the end of my rope as well.
I feel like there were 3 main things that made me fall in love with Windows Phone in the first place, but all of them are almost completely gone by now:
1, The unique "metro" design language with those endless scrolls of screens on the deep deep black of an amoled screen felt like you were holding a gadget from the future. I'll probably never be so awestruck by a phone like I was by my Lumia 800. This design has been watered up and gutted by MS through 8, 8.1 and now even more so with 10. The only thing that remains is the Live Tiles which I still love.
2, Reliability. Not only was I not able to remove the battery from my 800, but I never needed to. That OS was simply rock solid. Then you install WM 10...
3, The Nokia design. The colors, the unibody, those curved amoled screens... Then you see the 950/XL.
So, yes, I will hold on to my matt-orange 930 until I see if the Surface Phone is really the second coming of Christ, but if MS fails to deliver my Plan B is a top of the line Samsung with Android. I passionately hate Apple products...
