Re: It is not as if Adobe has not had good notice
I ditched Acrobat Reader on my Mac over a decade ago now when an update would not install unless I updated my ancient, barely working, copies of PS and Illustrator. Preview works perfectly well so who needs it anyway?
As for endless Flash updates requiring me to quit the browser, hell is too good for them. Cycling through purgatory and hell so they get a sniff of paradise before being plunged into the fires again for them.
