Love it, but I started using PT with this version. I love the new look, too (as already said, the color scheme is tweakable to make it look more 7.4-esque). The UI is a bit slow (especially if the plugin load exceeds like 50%) compared to other DAWs I am using (Sonar, Reaper). If you have multiple CPU-cores (I only have 2), you can limit the RTAS usage to fewer cores and then the remaining are available for the UI. If I reduce the cores from 2 to 1, the UI feels much quicker even under heavy RTAS-load, but then I run out of RTAS power ;-(.
I am currently in some kind of evaluation phase (PT?/Sonar?/Reaper?) and find myself using PT most of the time and getting things done and sound good very easily.
