Smartphone Adoption Continues to GrowSmartphone Adoption Continues to Grow

• Over 80% of world’s population has a mobile phone

• But only ~1/4th of the world’s population has a smartphone

Smartphone adoption still has huge upside for global penetration

Tablet Growth Has Been PhenomenalTablet Growth Has Been Phenomenal

• Tablet shipments surpassed DT/NB PC’s in Q4-12

� < 3 Yrs from Intro!

• Large screen computing device demand is strong

� Mix favors Tablets, not PC’s
