Ajax vs. Adobe Flex?

[drural]

Hi,
Has anyone compared Adobe Flex and Ajax? We're trying to decide which technology to use for a new development project. Any experience/advice you have to share might help speed our decision along.

We plan to modernize some older client/server (Powerbuilder) apps in our call center by moving them to the web. There are about 200 screens; lots of client-side validation, many screens are dynamic based on user role. Need to support quite a bit of heads-down data entry and some data has to be pushed to the client (real-time updates). Several hundred users.

Thanks in advance for any advice/experience you can share,
Andy

After doing PB 7 years in a row, our company spent 6 years in remaking PB for Ajax (or DHTML to drop the hype words). Everything went quite good ... until we saw Flex. There is this joke that yound composer in his twenties says "I", when he gets 30 he says "I and Mozart", then at 40 he says "Mozart and I", and at 50 he says "Mozart". If you go these days to www.faratasystems.com you'll see only Flex. Flex vs. Ajax? The very question is - and I do not mean to hurt anyone's feelings - absurd. Flex is a very deep product. Ajax is a go-do-it-yourself suggestion. Not a single Ajax product comes even close to Flex. Take it from the old PowerBuilder aficionado.

Kind Regards,
