With the Failure of RT, Microsoft Has to Move Back into the Direction of Intel
RT was Microsoft's grand design to get the transition of desktops to tablets back on a Microsoft OS. Now that RT has been demonstrated to be an abject failure, not due in small part to Intel's superiority over RT in all categories: performance, power efficiency and price, Microsoft has no choice but to move back into Intel's direction to try to get these devices on a real Windows platform.
As Ashraf has suggested, totally embracing a WinTel move into a 64-bit Windows tablet platform would provide an important advantage that cannot be matched on the ARM side and would be extremely appealing to the enterprise world because of numerous security issues..Extending this further into the smartphone category would provide for a complete Wintel 64-bit ecosystem.
At this point this is clearly Microsoft's best plan. Let's hope the new CEO is smart enough to stop wasting time and resources with RT.
This would be the logical action but Microsoft continues to defy rational thinking when it comes to product strategy. Look at the schizophrenia that continues in W8.1. It's like MS believes their product direction is handed down from the heavens and once received they're totally indifferent to rational thought.
