Adobe and Apple were once friends. Their relationship broke around 2000/2001 when one of the main guys at Adobe retired who was able to do deals with Apple. When Apple came back and asked them to make OSX versions of video editing software and photo editing software, they refused which led to bad blood between Apple and Adobe. Apple then made iPhoto, Garageband, iMovie, Aperture, Final Cut Pro, and Logic in order to combat the Adobe systems. iPhoto, Garage Band, and iMovie became the iLife suite that consumers know and love while Aperture, Final Cut Pro, and Logic became the defacto pro versions which were widely used by the most creative minds in their respective businesses.
Since that time, Apple and Adobe had not gotten along. Apple's applications just worked more smoothly and better than Adobe's applications. When it came time for iOS, Flash was not originally supported because Adobe didn't want to give Apple the APIs to make flash work on the devices while also doing the same to BB, Windows Mobile, and Android. That's right, you heard me, Android didn't have flash built in. To this day, BB, Windows Mobile, and Android have to install Flash Lite on their systems in order to get it to run. The experience is actually pretty poor on all of the devices and ended up throttling processor functions which caused the battery drain. To this day, Android users have to curb their usage of flash lite in order to not drain their battery life completely. iOS did not allow Adobe to create a Flash Lite plugin App for iOS since it would allow too much control over iOS and that would eventually allow viruses and malware to attack iOS. If you didn't know that already, you now know it and can check the facts online.
So now that Jobs is deceased, Apple can possibly work something out with Adobe but I highly doubt that they would endanger iOS by allowing Flash backend access. OSX computers that have flash compatible browsers are also at much greater risk for viruses and malware. Adobe's Flash concept had become too top heavy in 2011 and also created back doors for developers to invade your device/computer. Good job Adobe. It's not that they created a bad product concept, it's just that their methods were questionable and led to the decayed state of online animation. Hopefully Adobe will innovate and provide some awesome tools in the near future such as that incredible Sketchbook Ink vector graphic app that we saw at the demo. What iOS users really want are a capacitive pressure sensitive active digitizer stylus to be used on an iPad as well as Photoshop, Illustrator, Dreamweaver, Premiere, and the rest of the CS on an iPad because it would replace the machines that we currently use for content creation.
