Prettier, no, not me. It is a business app to me -- functionality, efficiency, accuracy wins over pretty pictures/tiles/graphics every time. I would gladly have taken (still take) the pmUA site since I found it easier to get things done than the newer CO site -- or even the CO version we just lost even though I missed the ability to search an itinerary "side by side" (in/out-bound) which was hugely helpful for when I needed to be on the ground for a single meeting.
