Well, during mixing, it can make it easiser to see envelope automations, wtach the faders n such, and effects windows can float there too. Agreed it is not the best use for screen real estate, but I find that splitting tracks across monitors can be kinda wierd. If ya aint done it before, do it and you'll see what I mean. But it ends up being a persoanl preferrence thing. Mostly I have effect windows up so I can tweak settings during playback. The console just ends up being there with my busses and master outs.
Conversley, I find that trying to work on a mix with the track view a bit cumbersome as I have the tracks sized so that the effects and other track controls are not visible. But I could do my stuff from there I suppose. Old habits die hard sometime. I do find that I can do more in track view and am using that more.
I dunno, mebbe it's just me, but I like console view.
