Personally I love flat and hate "realistic" 3D looking interfaces. Besides which, I wasn't drooling over the interface so much as the program and how it's shaping out....Geist is probably my most used plugin and it's almost become like an extension of my brain, it's such a great program, and the thought of it being even better in the form of Geist 2 is what makes me drool. I can't say I've ever bought a plugin for the UI design. The only problem I have with Geist is the interface being too small - the fact that this is now scalable is enough to induce a small pool of drool by my right foot (I always drool out of the right side of my mouth for some reason).
