John Dowdell posted a question on his blog about developers experiences switching to AS3/Flex. I posted a comment that I thought I would reiterate here: can anyone offer any compelling arguments for moving to FP9? You don’t have to convince me. I’m already there. But I have to convince the powers at work - Xbox.com / Zune.net - that it’s a good thing for them to do.

The sites are very design oriented. There isn’t currently anything that is data intensive where the performance boost of AS3 would make a big difference. The animations that are used are already optimized by using cacheAsBitmap where it’s appropriate so I don’t think there would be much of a performance boost there either.

We use XML throughout our site but I wrote an XML parser to handle all that for us with minimal effort so the E4X controls won’t make a big difference.

The only thing I can think of is that maybe we will make the entire homepage, or even site, a Flash app. In that case I believe that using Flex would be the best way to manage that. But that will be a long way off, if ever.

So, anyone have any suggestions?
