Agreed - Plenty of hitters have experience with it as well, since it's been around the minors for even longer than this season.
I saw it in practice a few times this year during spring training games, and it was _fast_. Add to that the fact that only pitchers, catchers, and hitters can request one (no managers holding the game up while the replay room checks on it), and it really won't slow the game down at all.
