If Apple has to stay true to the claims they made in the ads, they must allow ALL plugins. No exceptions. Unless the iphone renders a page the way the the page creator intended it to be rendered, its a watered down version of the page.
"This is not a watered down version of the Internet, or the mobile version of the Internet, or the kinda sorta looks like the Internet Internet. It’s just the Internet."
Unless Apple allows all plugins freely, the commercial was a lie, and Apple is liable for misleading viewers.
If Apple is concerned about resource hungry apps burning away battery life, they should have an inbuilt mechanism which warns users of every such instance.The choice of avoiding Flash and saving battery life should belong to end user.
