"there's no way this OS in its current and foreseeable state will ever be as useful as my 5-year-old clunker of a Dell laptop (or Mac for that matter)."
Thats an interesting statement...would you mind defining what you mean when you say "useful"...?
Basically anything beyond social media and entertainment. I'm a student in the sciences and the only notable advantage it has provided me with is the ability to use e-textbooks and read primary source literature without wasting paper or getting a headache. Of course, there's something to be said about the entertainment value, as I'm glued to my tablet a lot for web surfing and the like, but true productivity value isn't there yet.
