Ask any reseller what products gives them the
best margins any they will tell you top of the line.
That doesn't mean they sell more of them. In fact, it usually means the opposite. While most retailers would be glad to sell only Prescott systems when the chip is released, reality dictates that they will need to stock many more lower-priced models to meet demand.
Whether or not Centrino is selling well probably depends on what you mean by "well." If Intel keeps the price premium on it, then that probably means that sell-through is very good. (Though when AMD manages to keep a premium on its high-speed chips, that can only mean yields are bad :)
Start to worry about Centrino when you see $200 Intel rebates on it.
