I just think whatever they did to it on w10m was a mistake, the only improvement is the little cursor, 8.1 just felt better-faster and more accurate
we all know how tech goes, it needs to always be improving, but for some things, they are just so basic all you want them to do is never fail, 8.1's wordflow did just that, if they wanted to "improve" the already world's best -Guinness record- keyboard they should've tested it on the sidelines while keeping the original code for the official OS
there's a reason there's no half life 3, if you are a sane-logic driven person and you realize you cant go deeper than the earth's core, just save your energy for something else
