Smartphone 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 Faster Than Smartphones

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
