Computer trend follower : I assembled my first PC in 2007, untill now I follow up every commercial PC specs and new products.

Mobile : I used HP iPAQ & Dell Axiom at previous PPC era. Still, I have interests in mobile field including display, (camera) sensors and application processor.

Belief : Cost performance. Enough resources, that is just easy problem. I always think restricted, hungered and overwhelmed situations cause optimizations and that exited me. But paradoxically, I pursue man's dream ; looks useless but practical things like ARM's big.LITTLE mechnism.
