There’s an uproar at the moment on the interwebs. You may have heard about it.
The iPad will not support Flash.
Just like the iPhone before it, the Flash plug-in cannot and will not run in the iPad’s browser. Apple say it’s because the Flash plug-in is the single biggest cause of Safari crashes. I can’t say I’d blame them for being pissed. The window to the internet on your default install can be crippled by a third party proprietary plug-in. Not cool.
So, because Apple have a closed platform in the iPhone and iPad they can choose who plays ball.
