I suspect you're right about the basic nature of iOS and Android, but only half-right about portable consoles at least historically. Portable consoles have also filled the 'nothing better to do' niche in the past (Tetris was hugely successful on Gameboy) and this is where I expect they'll face stiff competition from iOS and Android. We'll just see less crap on portable consoles, and the players that put out quality titles won't be affected a great deal.
