Why is there so much noise over this? How many times does Flash have to die? Yes, the Flash plugin will be with us for another decade, but shouldn't most of us have moved on? I uninstalled Flash on my two Macs in December. I'm doing fine so far. Sometimes, I need to switch over to Chrome for video, but so far I'm not missing it.
I have relatives on Linux and this will complicate things for me. Basically I have to install Chrome and explain why videos and other stuff work only on Chrome. However, it is the way I prefer it by now anyway: use a Firefox without Flash for daily browsing and Chrome for Flash things.
Don't underestimate how complicated it might be to explain this to "noobs", though.
