I've always loved Prime for its atmosphere, catchy ambient music, good level design, good art, knowing to shut the hell up 99% ,etc. But the nagging controls were a mark against the game. Now, they're silky smooth and make the game much better. Its awesome using free look just to survey your environments without the original constraints. However some enemies and bosses have attacks that require the quick dodge during lock-on to avoid. Otherwise the button locks the screen which makes it quicker to hit switches and targets. The morph ball jump tied to waggle was added though, probably for noobs who cant figure out a double bomb jump.
