Intel releases PRO/Wireless 2100 LAN MiniPCI Adapter as standalone component: The wireless adapter that's part of the laptop Centrino system is now available as a standalone component for integration with laptops via the mini-PCI slot. Although Centrino is described as a system, it's actually a Pentium-M processor, some support chips for various management tasks, and a mini-PCI wireless adapter.
Broadcom has already made some strides in offering its own mini-PCI 802.11g and 802.11a/g adapter to PC manufactuers. Dell offers Broadcom's option for new Latitude and Inspiron models under its TrueMobile name. HP just announced a revision to existing laptops that allows consumers to add 802.11b or g (for $50 or $70, respectively). More announcements of this kind are expected soon.
Centrino is about branding and co-marketing dollars, so as long as Dell and others offer Centrino computers -- all three elements -- they can get the marketing dollars, while still selling Pentium-M + alternative wireless laptops.
