It has been hard to parse Microsoft when it spoke about its own phones (it is less ambiguous about iPhones and Android). But proof abounds. Look no further than Microsoft's own site, where Microsoft commonly had links to all offers from the various wireless companies. No such links are present now. Turning to AT&T and Verizon's sites, no Windows phone is listed. Windows phone is dead.
My Lumia 950 phones are just one year old. It's too soon for me to switch; it will be at a year, probably two, before I need a new phone. All the nice things I've said about the Lumia 950 are still true. All the nasty things I've said about Microsoft and phones are still true.
I'm no friend of Google but there is probably an Android phone in my future. iPhones are too expensive.
