I have it and I love it. My first bike computer was a Cateye which only showed two numbers at a time, so I had to push the control button often to cycle through everything I wanted to see. The Protege 9.0 displays all 5 numbers that I care about the most at the same time, so I only have to push it at the end of my ride when I want to see the additional stats and reset it for the next ride.

I really like having the temperature display. It's not always accurate when it gets hit by direct sunlight, but for overcast or night commuting during the winter months it's really helpful to know how far above or below freezing the temperature is so I know how vigilantly to watch for ice.
