Eh, I think Flash is overrated. It's cool, but for development - not for the web. It makes things like streaming video easy, and it's cool for animations and interaction, but I hate web sites built strictly in Flash. That's not the web, that's an abomination.
But yes, it's be nice to be able to run little flash games, etc. on Android, as long as they're presented as a native application. I'd hate to have Flash running in the browser. As long as there'd be a way to disable it, I'd be cool with having Flash support. But I don't necessarily want it or need it.
