I have the Dell D600 that has a Pentium-M (1.4Ghz, fast) and the new chipset...but it is not a centrino...why? cause I wanted 802.11B/G (for AE, which I have with my 12" pBook) instead of Intels 802.11B. There is no such thing as a Pentium-4m that is also a Centrino...but there are Pentium-4m based laptops that have WiFi of course.
Wifi has been available for PCs for a long time as well...but just not built in to every new Pentium-M based laptop like Intel has done. The good thing about Centrino notebooks/ Intel is that they are making WiFi mainstream...and that will benefit Mac users as well once hotspots are all over the place. Unfortunately, Apple made a commercial in 1999 that showed the Airport base as a UFO...when they could have been doing what Intel is doing now...showing "real world" uses.
