The 990 is the nicest looking remote they have ever made. The screen is bigger, and the backlight on the buttons is great. The buttons on the 890 are essentially unlit in comparison.
I show clients both models and let them choose which one they want. They pick the 990 at least 5 to 1.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
