Sorry, you’re inaccurate on Adobe having not written a 64 bit flash. Granted it’s preproduction alpha/beta, but it does exist. I know this because I have it on my Linux laptop.
That said; Flash, 32 bit or otherwise, is buggy and bloated, and I hate it. IMHO the sooner we can get rid of one more plugin, the better.
Thanks for updating my information. I would not put any mission critical work on alpha/beta trust... but then Flash is not required for any mission critical work.
