He even gets them to ship ahead of schedule. If only he enjoyed Duke Nukem...

I don't think it is fair to say Steve Jobs motivated Adobe. Yes, we've all seen the hundreds of articles basically saying "Steve Jobs thinks flash 'sucks' for various reasons and will never run on the iPhone OS;" however, it is clear that other companies, like Google, Nokia, ect., have an interest in Flash. Flash will run on the Android phones (for example), and I know Google has been "motivating" Adobe to get moving.

All in all, I would say it is safe to say Google has been a great motivator for the engineers at Adobe, not Steve. I would guess the engineers at Adobe could care less what Steve says, for they won't be helping him with his iPhone OS.
