Not only is it easy to manipulate tempo and time, it’s easy to perfect the timing of performances too. You can easily improve errant beats by quantizing audio to your session’s Bar|Beat grid, or to grooves extracted from other audio or MIDI performances using Beat Detective™, which offers better peak detection accuracy than ever before. You can also fine-tune “Elasticized” regions with precision control over each individual beat using the new warp track view and warp markers — you can even make the same precise changes across multiple grouped tracks while preserving timing offsets in multitrack recordings, such as with drums.

Beat Detective rules! And if Zumbido kept on on his Pro Tools versions, he'd know that Pro Tools 7.4's Beat Detective has improved sensitivity/accuracy!

I face away from the monitors while mixing. It bugs clients, but it doesn't faze me in the least.
