I have not read all the posts, but reading (and writing) music notation is a real asset if you want to work in a band with other (musical) instruments. TAB is fine for guitarists, but a trumpet player or a piano player cannot be expected to read it!!!
Simply put: Don't be musically lazy! Learn the LANGUAGE of music. If you can at least speak the language of music ... you are in. If you cant .............. :-(
As a guitar teacher, I hear this all the time: "Why do I have to learn music (theory/read)"? The answer should be obvious!
