Maybe, just maybe, this is occurring due to the fact that the Mobile version of the OS is now being aimed at the enterprise market? If I used them in the business world, which I actually do, what is left is all that's needed. All 14 devices run the bare basics. No third party apps, no twitface, don't need the fm radio as most car manufacturers supply them ;-) etc.
Kids corner I'm a bit miffed by though, although the store does now include age ratings for games etc. Again, this seems to be "clearing" out the junk for an enterprise environment. Good or bad? Who knows, but from my perspective, W10M is great as a business tool, and the RS builds are another step forward
