As you're probably aware, the Apple iPad, like the iPhone and iPod Touch, doesn't support Flash. Apple has its reasons for this, but clearly Adobe isn't happy about it. Here's their response.
It looks like Apple is continuing to impose restrictions on their devices that limit both content publishers and consumers. Unlike many other ebook readers using the ePub file format, consumers will not be able to access ePub content with Apple's DRM technology on devices made by other manufacturers. And without Flash support, iPad users will not be able to access the full range of web content, including over 70% of games and 75% of video on the web.
If I want to use the iPad to connect to Disney, Hulu, Miniclip, Farmville, ESPN, Kongregate, or JibJab — not to mention the millions of other sites on the web — I'll be out of luck.
Adobe and more than 50 of our partners in the Open Screen Project are working to enable developers and content publishers to deliver to any device, so that consumers have open access to their favourite interactive media, content, and applications across platform, regardless of the device that people choose to use.
The main arguments against Flash running on the iPad is that it's a resource hog and a security risk. Both true! Hopefully the web is moving away from relying on Flash for videos and ugly menus, with HTML5 acting as a more-than-adequate replacement. But we're not there yet. While I can appreciate the fact that Apple is trying to keep the iPad more stable by not including Flash, the fact that it kills off most online gaming and video streaming in the process makes the trade-off questionable.
