Just thought I'd chime in again.
Got the Hue. Incredible system.
The app is slightly less complex than I'd like it (very basic and no way to set general fading moods which would be so nice) but otherwise it is incredible. The setup is horrendously easy. Plug it all in, press a button, done.
The greens are slightly whiter (and less deep) than I'd wish, and browns are a bit more subdued as well, but the rest of the colours (especially purple, red, and blue) are absolutely gorgeously rich and amazing for setting the mood of a room. The Light Recipes are pretty nice too.
