People were excited about it, it was making forward/upward progress for a few years. Microsoft bought Nokia, and people got even more excited.
Then what happened? Years passed with no flagship phone, literally no reason from me to move on from my Nokia 1020 because there was no hardware to move to. Then they announce that older models weren't getting the Windows 10 update, which was another nail in the coffin (not to mention a big "fuck you" to the fans that have stuck with Windows Phone this long). Now we're hearing basically... nothing at all about anything.
I loved Windows Phone 7 on my HTC Titan II, and I love Windows Phone 8 on my Nokia 1020. But unless a really killer new phone is in stores before January 1st, there's basically no way I can stick with Windows Phone for my next phone.
