I also prefer HTML5, and would hope that nobody is building new products for Flash today. I waited months from my last OS install to add Flash to this system...partly because I distrust Adobe, and partly because I didn't want the hassle of dealing with upgrades. Also, it used to be ornery to use Flash on a 64 bit system, requiring installation of 32 bit libraries (which yum/RPM handles fine, except during OS upgrades)...and I was afraid that was still the case. But, that issue is gone, and they provide a 64 bit build.
