The problem is that Intel will be the only good chip maker and ask way too much for them. They'll have a monopoly.
x86 PC and laptop sales projections for 2015: ~260 millions, falling by ~8%/year.
Tablet, smartphone, netbook, etc. sales projections for 2015: over one billion and still growing annually, albeit slowing down, most of it using ARM-based CPUs
Intel might be a monopoly on the x86 desktop but desktops are slowly falling out of favor. Both of my sisters and their boyfriends do practically everything on their phones and tablets instead of their laptop or PC.
Unless Intel manages to carve a significant market share in mobile computing, they could be in trouble a few years from now when the majority of personal computing will have moved to ARM-based platforms.
