All the hullabaloo is about adding a little topspin on the forehand which the player can pick up by watching any match on TV or from the 1000s of free videos.
I would agree that the difference between an old school and modern topspin 1hb are minor, mostly grip and swing path (don't get me started on the 1hb slice), and that the technique for volleying, serving and smashing are virtually the same. But, the forehand is significantly different, as is the 2hb since it has evolved to be basically a left handed forehand with some assistance with eye-hand coordination from the right hand.
