Why another MS should pull out thread.
For the next couple of years all is good. W10M is an alpha / beta release. It isn't going to work as you would like. If more people read the warning BEFORE getting exited, it clearly states that it isn't a finished product.
From what I can gather, it is a ground up development. Unlike android where updates are basically fixes for bugs ( and there are many ). Lollipop, was again, an upgrade from 4.4.4. There isn't a lot in it. The biggest change was ART replacing Dalvik, and then trying to pretty it up. Still android, running a Linux kernel. Apple does what apple does best. Rehashing of OS and devices. They have FULL control over you, and devices that fail / warp at the first sign of rain. They are selling you a lifestyle.
I came from android, where I cooked roms For me, the windows environment is pretty easy to navigate, it doesn't want to know your inside leg measurement, like google, and the devices don't break when subjected to the mildest of knocks.
The other 2 OS companies need competition to keep them honest (sic). With the right marketing (yeah, I know), and actually getting them instore so people can have a play, continuum, Astoria etc, things may look up. Oh, and get the office apps off of android market, unless google play ball
