Japanese?

"US and Japanese companies now dictate the market."

What Japanese companies? Apple, Google, Microsoft, HP/Palm and Motorola are American. HTC are Taiwanese. Samsung and LG are Korean.

The only Japanese company I can think of that has a presence in the market is Sony Ericsson, and a) it's a joint venture between Sony and Swedish Ericsson, and b) they hardly have the market penetration at the moment necessary for them to start 'dictating the market'.
