The huge Ion customers are...
Jensen Huang, the CEO of Nvidia, has confirmed that Apple, Acer and Asustek are huge Ion customers. He did this during the company's Q1 2010 financial conference call.
The blurry part is that in the same answer to analyst question, he tells that 9400M and Ion are the same chip, while we can directly tell you that Nvidia marketing and communication part advices people otherwise.
Jensen said „Apple, Acer and Asustek are huge Ion customers“, and time will tell if Asus plans a secret Ion based product. Maybe he was thinking about Nvidia's 9400 chipsets that they are buying?
