Surprised there hasn't been a thread about this already, but Windows 10 S is "the future of Windows." Essentially, MS has decided that they need to compete with Chromebooks, so they've come up with Windows 10 S, a stripped down version of Windows, where you can only run MS approved apps and where your files are often stored "in the cloud." For those of you who were wondering what the "catch" was with MS offering Windows 10 for free a while back, it looks like we've found it. Now, MS says that you'll be able to pay $50 to "upgrade" to the full version of Windows so you can run apps that won't be found in the app store (like Chrome, iTunes, and a whole host of other programs), but there's no telling how well they'll perform, and if you're somebody who uses Linux or certain admin tools, you'll be SOL. It's not really clear if a full upgrade will give you those tools or not. Hopefully, this will turn out to be an even bigger flop than Win8 was (because who wants to only use the Edge browser and Bing?), but if they get traction with it, then you can expect them to gouge you on everything in the future.
