i've been reading bits of it on and off the past couple of years (before, during, and after an LA course at uni) and STILL i find something new and worthwhile in it. the exposition is crystal-clear, i don't think i've ever once been lost in any passage of the book, everything is perfectly explained and motivated. what few of the exercises i've done are fantastic, i really should come back and do as many as i can. this is the creme de la creme of mathematical exposition and few textbooks compare
