personally i would only use cortana if driving or something
Hmm never thought of that aspect usually I write cortana off as irrelevant to my life but I guess there are times when I'm working on some electronics stuff (soldering iron in hand, etc.) and referring to a datasheet or schematic on my tablet and could do with looking something up without putting down whatever I'm doing (which is often fiddly).


but then I've extensive usage of OSes/UI replacements that probably the average person isn't so familiar with.
