I have to think, have to dream, that MS is doing something to make a x86 6 inch phone that runs Full Windows. If they do that AND get it on all carriers it will be a huge success, But Windows 10 Mobile is essentially dead. No carriers even have them and the number of users that buy phones outright are too small of a factor.
I know people say it's a challenge, but the battery life seems to be the only issue for me. I have a 7" HP Slate full Windows. Why can't MS or some OEM get one down to 6 inches and cram a phone in it. There would instantly be a ton of apps for it and I think they would fly off the shelves.
But if MS continues with Windows 10 Mobile, well, nothing's going to save that ship.
