The problem that Google is anticipating, and always one step forward, is because, Microsoft has the ground on PC OS. the integration on mobile with PC is kinda suck till now. Even theWP 8 to Windows 8 for PC does not have a direct integration, WP 8.1 and Winddows 8.1 might be the solution. I guess this is the reason Google is very agressive on this. Holding the Dual Boot OS from Asus might also pave a way for people to figure out that we can have both OS running on the same device...
