Another Ultrabook feature: Free wi-fi

Intel is working a deal with Devicescape for Ultrabooks

"Devicescape’s method of getting devices onto free Wi-Fi networks is clever. Basically, it lets a device automatically join a free Wi-Fi network, even if that network typically requires some sort of manual input to join. It achieves this feat by sending a specially-formatted DNS query that can worm its way past any Wi-Fi router that’s not hyper-fortified. The query then heads to Devicescape’s servers, bearing details of the Wi-Fi point; then Devicescape’s servers send back tailored instructions on how to gain access to that Wi-Fi point. Devicescape’s software on your device is then able to link you--automatically."
