Windows 7: Windows 7 to Get 64-bit (x64) Firefox

Well perhaps that was the wrong word, i believe the term is "better the devil you know" i imagine alot of them will keep using flash because they are familiar with it, unfortunately not everyone is willing to learn to change the way they do things (again think XP)

also think of it this way, some pages will need to have quite a revision before they can support anything but flash.

also we would have to wait for more browsers to pick up this awesomeness

Adobe CS5 is great (and x64) and so is Adobe Lightroom. Everything else they make is a bit crap imho
