While the iPad boasts a lot of features, one of them isn't Flash. The Adobe plug-in is nowhere to be found on Apple's device, meaning that many online games and video sites (such as Hulu) aren't usable on Apple's tablet device.
Don't think Adobe hasn't noticed this omission. In a stern blog post, the Flash team praised the inclusion of PDF and ePub support in the iPad, but quickly went on to condemn the company Steve Jobs built:
"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."
Adobe is calling out one of the biggest gripes developers have with Apple's App ecosystem: its restrictive, closed environment where Apple must approve all programs that run on its platform.
