The people who fix your computers or help you over the phone are the family friends who are geeks/programmers. Once the geek herd has moved on to something else, then the mass follows whatever they're currently using, because they're the ones that advocate the change. It will take a few years, but once Google has lost the geek vote, they will die a slow death like Microsoft did. At this point my money is on Microsoft taking the geek mindshare back.
This looks exactly like what happened when Chrome started killing IE.
