I have a 900 and a 950 to control two seperate systems.
The 900 would fulfill the needs of either systems but I do like the 11 digit ability on the lcd of the 950. The rechargable battery is an added bonus. The larger, more flexible lcd display with the ability to change the backlight colors and the auto backlight(actually there is no display until you pick it up) would probably be the main reason I like the 950 better.
I recently added lighting contol to the 950 in the house. Thats were you may run out of 'power' with a 900 depending on how many activitys you have set up and the amount of lighting control you have.
I thought I would never replace my 850 but the 900 is better and the 950 is that much better than the 900.
If all you want is a rechargeable remote, it may not be cost effective.
If your always looking for new things to control with your remote(as I am), the 950 is money well spent.
Every day is a good day.......some are just better than others!
