My next phone will be running windows 10 mobile, if they support their phones as well as they do the desktop.

And you are aware Windows 10 mobile is just about dead right?

"Windows 10 for phones has had a catastrophic Holiday quarter as sales slumped to an all-time low to just 4.5 million Lumia phones. That's a decline of the whopping 57% over the same quarter in 2014, and 49% drop in revenue."

Oh, and you should probably read this too:
