The author seems to want Win 10S to succeed because it will result in better Windows Store apps, with a simple install process, which can be used by all Windows users.
Right off the bat, doesn't this place an unreasonable amount of confidence that anything coming from the app store will not be evil?
Secondly, all my problems with Windows 10 have been outside the Windows Store experience that I don't see endearing the product to the education market. I have a couple of Win10 machines with 32GBytes of eMMC; doing an update is hell as it requires an external USB thumb drive and takes multiple hours - something that can't be tolerated in a classroom environment where there are dozens of PCs. I've bitched about my problems with the Win10 Bluetooth stack and I don't see anybody in Microsoft fixing that, even as the need for BT is growing with different external devices.
Next, I feel like Microsoft is going to continually look for opportunities to monetize the platform. Office 365 revenues flat lining? Say, let's start charging all those kids using Win 10S machines, the schools are just wasting money on hot lunch programs that should be going to Microsoft.
Finally, there is the privacy issue. Win 10 seems to be designed around collecting user data and exploiting it. Is this something parents want to have happen to their children? You can say that Google and Chrome do the same thing but it doesn't seem to be a core part of their business model. I wouldn't be surprised coming home to a kid that is demanding an Windows OS'd phone because the computer at school told them how much better it is than their stupid Android or iOS phone.
I know I'll get replies from numerous AC's who feel that I'm being unreasonably harsh towards Microsoft and what they're doing with the Windows 10 S platform, which is much better than ChromeOS even though nobody's seen it before but I just don't see Microsoft having the right stuff or approach to take on the education market in way that is positive for students and not completely exploitative.
