Ok, if I made a website praising the user interface, I'd make sure it'd live up to the expectations. The gui isn't as good as google sky imo - the controls are pretty bad, the "smooth panning" is far too smooth.. disabling it isn't fun either. The gui also take up a large portion of the screen. It's still ok on a 5:4 screen but I can't imagine it to be fun if you have a 16:9 tft.
Other than that it's pretty cool. You get to see infrared, ultraviolet and other imagery that you don't have in google sky. The position of the objects is displayed in real-time (relative to your location).
It's useful. I don't know what made them think their gui was that good though.
