I knew absolutely nothing of Centrinos until about a month ago when a replaced my new AMD 3000+ Laptop because I was a bit disappointed with the overall setup of it.
I am now quite satisfied with my Centrino, it does remarkably resemble AMD architechture from what I understand, and it's actually quite a nifty little machine. The Centrino will actually run at a certain temperature without any fans spinning, and I mean none. Once it reaches a certain temperature, which I believe is over 50 degrees, the fan will kick in and cool down the processor. I was pretty impressed with this little technology Intel rigged up.
