AMD never had the scale or software or branding to create a differentiated platform. They behaved as a commodity component supplier and were treated as such.
Apple can differentiate with software and services and user interfaces and use their brand to differentiate. Remember when the iPad first came to market? It was seen as just a giant iPhone of limited value.
Who would want one of those instead of a much more feature rich and higher performance netbook?
Surface Pro ... delivers an appreciably quicker user experience. Apple does get fairly close in some cases on far slower hardware, which should concern Microsoft quite a bit should Apple ever choose to go ahead and build a tablet/notebook convergence device of its own
What will ARMv8 do with "good enough" performance that AMD's Bobcat with 64-bit "good enough" performance couldn't do?
Are you for real? Haven't you heard Android is going 64bit OS? Or iOS will run 64bit next year? Maybe that's the point of ARM v8...... and that means ARM v8 will likely outship Intel core chips five to one over the next five years, at a fifth of the price.
