It looks fantastic and it could have been written with HTML + Ajax, but I guess ( because I don't know much flash my self ) they site owners felt more comfortable with Flash and thought it would be easier ( once again, I guess this happens when you have thousands of flight hours with flash )
Judging by the status bar, it seems that most of the images and text are downloaded dynamically ( otherwise the flash file would've been too heavy )
What type of webapps should consider do all the frontend in flash?
Would it be easier? Yes/No, only if you suck at HTML+Ajax but you excel at Flash?
Is that for everyone?
When it should not be used?
I guess that an extra benefit is that you don't have IE+FF+Opera+Chrome+Safari compatibility problems
Would this be the next programming model for webapps front end?
