Only one HUGE problem with the article... the iPad is a console. What has always seperated consoles from computers since the introduction of the NES is that a computer can install and run and and all code that the user chooses to use. A console on the other hand has DRM baked into the system and is limited by the hardware maker as to what it can and cannot run/do.
The iPad is just the newest generation of console like the Gameboy, PSP, ect... Its entire design is limited to what the developer of the hardware tells you/the hardware what you allowed to do and not allowed to do. While you can jailbreak the iPad, it's not always easy and it keeps getting harder. The same can also be said of modded a console. And like modding a console is illegal, Apple has been fighting tooth and nail to make it illegal to jailbreak their devices (http://www.wired.com/threatlevel/2010/07/feds-ok-iphone-jailbreaking/
) and they are still pushing to remake it illegal to jailbreak any iOS device under DMCA laws.
So as long as people continue to by devices that are crippled by the maker, then consoles will still be around. They are just taking on new shapes and are trying to avoid the image of a console being only for games (which the PS2 and beyond have shown they can do more then just games).
