Steve Jobs has taken a break from his iPad e-mailing spree to post another long, open letter to Apple's website, this time about Flash. The letter goes into detail as to why Apple chooses not to allow Adobe's Flash technology on the iPhone and iPad, claiming that the decision isn't as business-driven as Adobe would like to believe.
Jobs' opening remark is about Flash's openness, or lack thereof. "While Adobe’s Flash products are widely available, this does not mean they are open, since they are controlled entirely by Adobe and available only from Adobe," writes Jobs. He acknowledges that Apple has closed products as well—namely the iPhone, iPod, and iPad—but that the company believes that all standards on the Web should be open. Naturally, this leads into Apple's support of HTML5, CSS, and JavaScript, not to mention Apple's support for the open source WebKit.
Jobs also believes that Flash isn't quite as dominant on the Web as Adobe claims, noting that "almost all" video that is available in Flash is also available in H.264. YouTube is among the most successful apps on the iPhone OS, Jobs points out, and there are numerous other apps that support video streaming available for the iPad (Netflix, ABC, NPR, New York Times, and more). Again, Jobs makes the concession that iPhone OS users won't be able to play Flash games, but says that there are plenty of other games on the App Store. (Someone let me know when there's a version of Winterbells for iPhone.)

Later in the letter, Jobs notes that many Flash elements and websites are designed with a mouse in mind, not a finger. This much is true—even of my beloved Winterbells game—though that's largely the decision of the designer and not the technology.
Then there are the old performance, battery life, and reliability angles. Not only does Flash continue to be a vector for cyber attacks, Jobs claims that Adobe has been completely unable to show Flash performing well on any mobile device. Battery life naturally ties into this: "To achieve long battery life when playing video, mobile devices must decode the video in hardware; decoding it in software uses too much power." And then, finally, there's the real issue with Flash, according to Jobs: it puts a third-party software layer between the platform and the developer, and helps developers fail to achieve their full potential as iPhone, iPod, and iPad app developers by offering cross-platform tools.
Many of these points undoubtedly irk Flash supporters. He does make one point, though, that is quickly becoming truer by the day: there's an "avalanche of media outlets" offering content without Flash, largely due to the iPad. With a Hulu iPad app around the corner and YouTube, Netflix, and many news sites already adopting other, iPhone-friendly video formats, consumers have little reason to continue demanding Flash compatibility except on principle.

Developers, on the other hand, aren't likely to be so willing to buy into Jobs' reasoning. After all, there are plenty of ways for developers to use cross-platform tools in order to create perfectly workable apps, HTML5 video doesn't necessarily guarantee better performance and battery life, and some Web developers will continue to create sites that are geared toward mice and not fingers.
