In a recent post Steve Jobs talks about his thoughts on flash and why it is not supported on apple’s mobile devices such as iphone and ipad.
“Adobe’s Flash products are 100% proprietary. They are only available from Adobe, and Adobe has sole authority as to their future enhancement, pricing, etc. 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. By almost any definition, Flash is a closed system.”
