Horseface, I caught a demo of it last week and I'm a lot more interested now.
The fidelity is great, but that was expected. All of the little touches are what put it over the top for me - the pop-up menus, the bookmarking functionality, the timeline - all nice touches that will definitely improve the user experience.
I'm as excited about the uncompressed audio as anything - although I don't have 5-channel discrete in or HDMI on my preamp, unfortunately.
