Even though search engines poorly try to index flash content it is just not resulting and more and more people (devs) became aware or have known from day one the many cons and the few pros of using flash at all.
I have to admit not "allowing" Flash at this point in our site projects.... One of the first things a client looks at with their new layout is the display on an iPad or phone. Seems to me you are asking for trouble using Flash.
The usage of Flash and all the arguments for or against is historical, and I don't think any of this has changed. It's never whether or not to use it, it is, and always has been, **how** you use it.
Flash will be with us for a while. As one who's coded it extensively, there are things you simply can't do with other existing web objects. The problem again is HOW you do that.
An advantage to this - many visitors will view the less dynamic content and wonder how it would be with the bells and whistles, and are often prompted to enable JS or install Flash. So it's a good selling point. You put the effort in, it inspires the visitor to do the same.
Now that we can do video with HTML5 (and Jobs vowed Flash will never be allowed on Macs/iPads,) we can start to eliminate video with Flash (or at least, eliminate it when the HTML5 draft is finalized in 2014.)
But that doesn't mean Flash is going to die, or be useless. There are still things it can do you can't do in any other way.
It is not only Apple any more. There is no flash support in the new Android 4.1 Jelly Bean and nearly a week ago Adobe have unpublished the Flash Player from the Google Play Store. Flash is officialy dead, at least on mobile!
I implement flash very rarely, but one excellent use is shrinking images before upload to a server. Flash seems to be the best tool to use... and I'm sure there are many other examples where that's the case.
Flash is the best 2D animation software available according to the latest technological trend.It is used to create animations for gaming,cartoons and flash banners for the websites.It is very user friendly compared to other 2D animation soft wares such as Flax,Swish etc.
IE 10 Metro not supporting Flash unless it is whitelisted is a pain in the butt too.
It seems that Flash was to be dropped entirely from Metro, until that decision was changed at the last minute (which may explain why the silly whitelist exists).
I'd much prefer a clear-cut answer from the major players (MS, Google, Apple, even Adobe) about their future intentions - just a yes or no. Having to predict who is going to support what is daft. But that's not going to happen, really.
Until I get more confidence in where Flash is going (in terms of where it is supported), I'm trying to cut all ties with it.
Apple's trying to drop it. MS is trying to drop it. That's a pretty big proportion of the online world, right there.
My completely uneducated guess: Flash dead by 2015.
