Personally, I would not go out and buy an Air Integrated computer. However, since I got a great deal on one, I have been diving one lately. I like having the pressure on my wrist rather than having to look at the SPG on my hip. Since you already have one, dive it.
I also carry an SPG and a bottom timer. I have had two separate computers fail on me in the last three years. One was on a dive vacation to Bonaire. I'm glad I had my bottom timer and tables, since I did not have to miss a dive.. (I also have a watch, in case the BT goes).
Keep in mind, ALL gear can fail at any time. Yes, you can abort the dive, and then what? According to "the rules" you sit out of the water for 24 hours. If you've paid several hundred dollars a day to go diving, then why not carry a backup? At least a bottom timer, or watch, and an SPG. We carry redundant Second stages for our buddy. Why not carry redundant gauges for a high failure item like an AI computer?
