I notice that, if given the choice, I'll almost always pick an HTML version of a site over Flash. It's not that I'm not Flash-enabled. Or even that I don't like pretty, shiney things. But I guess my experience with Flash thus far has led me to expect frustration due to the passive sit-back-and-don't-interact design that so much Flash stuff adheres to. Maybe this will change as (if) people start doing more useful interface stuff with Flash, rather than just using it for...um, flash.
