It's not a strong response. Heard it and ignored it--Sass only points out that he has stories of other people say the UI is "relaxing".
Subjectiveness aside, though, my real issues are with Adobe eschewing native windowing and controls to reinvent their own UIs. I'm much more interesting in the apps just behaving as expected than how they look. For example, EVERY time I unplug from my monitor, the windows of the Adobe apps fall off the screen in a way that can't be recovered. They may even be faster than previous versions, but the UI makes them feel bloated and foreign.
