Does flex have a long expected lifespan

EDIT JAN 2014 - No Longer relevant answer has been played out in the mean time.

This is a cross post. I've already posted the question to flexcoders.

We work in flex as a technology. However a potential client has stated that they are worried about the lifespan of flex as a technology. Especially as apple doesn't support it on their mobile devices, and the increasing support for HTML5 within browsers.

What开发者_如何学Python I would like is to be able to show them some figures about any large adopters. Especially in enterprise. Just to show that it isn't some flash in the pan technology. (No pun indended)

For those interested you can view my original question.

There are many very large enterprises using Flex. Check out some of the testimonials and the Flex Showcase.

Does your client deal with video? If so, then it is likely that over the course of the next 5-10 years the HTML5 video tag could replace Flash as the default video player on the web. However, even if HTML5 chips away at Flash's relevance as a video player; why would that affect Flex's ability to provide a Smart Application GUI?

Does your client build games? It is possible--although I believe unlikely--that the HTML5 Canvas element will be used for a lot of web games. IF this aspect of HTML5 chips away at Flash's relevance as a web game platform, why would that affect Flex's ability to provide a smart Application GUI?

Additionally, why did your client choose Flex over an AJAX solution? Would the same reason apply to an HTML5 choice?

It is also probable that Adobe will keep innovating The Flash Player and Flex faster than HTML5. Flex has a mature toolset with lots of support.

I'd also ask why is it important for your client to provide applications support on mobile devices? The answer to that question will have a big affect on the client's decision whether to use Flash or not.

I don't have any specific numbers or case studies to share, though. YouTube had a Blog post about why they chose Flash. So did Hulu. Of course, I do not know if either of them are using Flex.

This should be an large adopter: SAP
