Hmm. Well. I guess you spend most of your time shopping for shoes and browsing movie sites..?
If you look at your sample site
http://www.avatarmovie.com you'll see a lot of that site's functionality is actually javascript, like the drop down menus. But most of the site requires flash. Nike uses flash on desktop systems but they actually have a pretty nice web site coded for the iPad too
As for the Disney site, as I said, since you don't have an iPad you're not getting the iPad specific site, you might try surfing to
http://home.disney.go.com/mobile/?device=ipad to take a quick look, might not work right on your desktop though. :chortle:
The site you get on your iphone is:
http://home.disney.go.com/iphone/index and it doesn't seem very "dumbed down" either. But that's your opinion and you're entitled to it.
