I agree that this forum and its members are a huge benefit.
As far as SONAR, I went from 8.5 to X2 and the experience has been a life changer. The power and the included plugins have always been a given plus, but for me, work flow suffered when sizing, resizing, opening, closing, moving windows made the experience more tiring than it should have been. I was constantly chanting, "Where is that friggin' window...? I need another monitor...". The X(*) interface changed all that. AutoZoom, Smart Tool, Track Lanes, Screen Sets, Docking and, of course, the ProChannel strip have all made so much sense to me and made my sessions a lot more enjoyable. Now, instead of another monitor, I'm thinking a single, bigger monitor would do it for me :-)
