Actually tested 13+ hour battery life running windows s?
Well I wouldn't say its the future, but its certainly current. That's best in class.
Windows s, however is not the future, its a niche OS that suits some people and not others. You want Netflix, browser, email, and some office work, its got you covered.
Actually that will fine for a lot of people. (Although to be fair, you don't really need 8gb of memory and an i5-7 processor to do any of those things, doesn't hurt but...)
You wanna do hardcore gaming, use adobe, program, write music, make databases for oracle - not yet. Store has to grow and it will.
Really the biggest obstacle will be gaming. MS has to sort that out with the game stores, find a way to bring them into the fold.
UWP generally is the future though.
