mmm... 4 million shipped already... that would 40 days of production at 100,000 a day. But they did say that they are now ramping it up to 100,000...
Keep in mind that the world has 6 billion people. Intel has plants in germany, and many other countries. Those 100,000 are split between the US market, the european market, the communist markets, and all the smaller markets around the world. And what goes on the market is used in more then just PCs... xboxes and laptops. And many go straight to system builders like dell who use them to build systems, which will then be sitting in warehouses and stores shelves all over the country.
So I would guess no more then 20k (maybe even 5k) of those 100k a day get to USA stores. And those are snatched right back up due to the high demand generated by a 300 million people (and many businessness etc) market.
do a little math... Most households are 4 or 5 people... and they can easily have multiple computers... I would say easily 50mil to 100mil personal computers in the USA. if only 10% are looking to upgrade their computer at the moment then that is a demand of 5-10 mil processors. If only 5k hit the us market per day, it will take 1000 days... and thats not even considering that the E8400 is just ONE of the processors from the 45nm line. there is also the 8500, and the C2Q extreme, and the E8200 (is it the 8200?)
So 100k is NOTHING.
