That was sort of what I remember. I completely skipped all 6.x versions and only went back with V7 when their computers were starting to get decent again (as in making the switch from PPC to Intel). Fortunately, I should add, because most of 6.x was a desaster IMO. And fwiw, at the time Emagic was bought, tons of people were switching from Apple to Windows boxes, simply because the 5.x versions were running *way, way, way* better under Windows (hence some pretty sour feelings). I even couldn't believe it myself how lame of a duck that G5 was that I had to configure for the local music university's media lab, compared to my homegrown PC, slapped together by pretty cheap components.
During that time, I almost switched back to Cubase, simply because I couldn't justify shelling out tons of money for a machine that'd be slower and less reliable than what I already had. But fortunately, Apple made the Intel switch and that little Macbook was good for an experience comparable to my new MBA.
