'A while now' being long enough that I might expect some notable impact on Google's business by now. I do agree it could just be too early.
My iPhone/iPod timeline is referring to the time it took for the iPod's sales to be severely impacted [1]. I'm not disputing that the iPod continued to exist for a long time, the iPod Touch wasn't discontinued until 2022, but it was a pretty meaningless part of Apple's business by that point.
