Are YOU kidding? Name me ONE thing that's useful and based on Flash? Ads? Video players that use a ton of CPU? Whole websites based on flash (that should have a non-flash version btw)?
Give me a break. Flash is useless!!! In my daily life the only place I see it is for browser ads.
You are right and wrong at the same time.
Flash is genius that's completely underutilized and poorly utilized. It's the only auto-scaling resolution independent vector based container for the internet- but it's rarely used that way.
Flash splash/home pages are 100% wrong as UI. Sadly, that's how much of Flash is used. Jakob then fixed it a few years ago but it's now used mostly as a container for still images and some animation.
I could go on.
