It is interesting to see, Live Documents chose to use Adobe Flash/Flex as front-end technology.
I read Zoho guys on Flash, I understand, it makes sense to use a technology that doesn’t have dependencies, easy to develop with, saves time, provides better experience to user and good for business. If Zoho guys think, they are achieving these goals with technologies of their choice, it’s totally fine. I would love to see how they respond to Live Documents release.
But hey, there are some (Live Documents, Buzzword, SlideRocket etc) which think Flash/Flex is cool (faster to develop, easier to use, consistent experience and better for business).
