After talking to some of the Avid reps at NAMM this past Thursday, I made the plunge and loaded 10 yesterday. I'm enrolled with Berklee Online in the Mixing and Mastering in Pro Tools (one of four courses for their Professional Certificate in Pro Tools), and the teacher of that course also gave a huge endorsement for upgrading to 10. So far so good. I spoke briefly with Martin at the show as well. Great guy, and great people at macprovideo! Even with the excellent 101 and 110 PT classes through Berklee, I get a lot of info from macprovideo. Indispensable. Thanks! SG.
