As much as I like Flash, I do agree it's way too proprietary, and new mobile devices are starting to deprecate or even outright drop support for the format.
I only get a missing plugin error as it's looking for Flash. And yet that plugin isn't supported in my phone, even though it is more than powerful enough to render such stuff.

BTW, my phone's a Samsung i5500, if that helps.
