Intel has decided not to include 3G functionality on its upcoming Centrino notebook platform.  

The company had previously intended to build in an HSDPA wireless access module from Nokia, but has decided to opt for a less costly fast WiFi option instead.
The new Centrino platform, codenamed Santa Rosa, will be launched in the second quarter of 2007.
The new platform will include Intel's Next-Gen Wireless-N card, an embedded network adapter based on the IEEE 802.11 draft-n standard and which also includes a, b and g standards.
This will allow notebook users to share five-times the data at twice the range of their existing systems.
The following version of Centrino may well include the HSDPA option as well.
