Texas instruments is claiming the launch of “industry’s first quad-radio single chip,” which throws 802.11n, GPS, FM transmit / receive and Bluetooth radios onto a single 65-nanometer WiLink 7.0 solution. Supposedly, this device reduces costs by 30 percent, size by 50 percent. No current prototypes have been reported to have been tested but with Macworld round the corner an implementation is not such a faraway dream.

Remember the most recent Macbook refresh, the one which included a discrete GPU by Nvidia along with a higher end Nvidia 9Series graphic card?? One of the main user gripes with this awesome solution that boasted the best of both worlds between Nvidia’s two implementation(one for higher graphic requirements and one for usual no graphic stuff) was that to change between the two, one had to log off and then relogin. Usually to change between the 2 included a 5-10 second delay.
This is being resolved by Nvidia’s latest Optimus Technology that implements superfast switching between Intel’s graphic processor and the Graphic card, such that you cannot notice the switch.
