Intel is on the verge of serious marketshare gains in mobile.
I predict marketshare will make "Intel can't compete in mobile" claims look very silly by the end of 2014.
They've been "on the verge" for several years now.

I see them struggling in the mobile (phone) space to be honest, due to entrenched market players. They're obviously not going to flip Apple to using x86 unless they show MASSIVE cost and performance benefits over Apple's in house designed chips (like 2 to 3x improvement). They've got a foot in the door with Android as the VM model makes it much easier to move in, but they still have compatibility issues. If a company ships a flagship phone with an Intel chip in it, they're going to get slated for slow performance in apps using native ARM code (i.e. games) as they have to be binary translated, which costs.
But they should do very nicely in the tablet market. Windows 8.1 plus a Temash or Bay Trail chip? Sounds like a great tablet to me. Very easy to sell it based on "and it runs all of your existing apps already!". Basically the opposite of the smartphone situation- x86 apps are entrenched in desktop and laptops, and pushing down into tablets (and hybrids).
