Abstract: One or more removable storage devices inserted into a computing device store a number of different preinstalled operating system instances. The computing device has a number of logical partitions. Each logical partition is independently executed on the computing device. Each logical partition is mapped to and uses one of the different preinstalled operating system instances. As such, a given preinstalled operating system instance to which a given logical partition is mapped is used by the given logical partition without ever having to be installed on the given logical partition.

Abstract: A WiFi sales reward system provides WiFi Internet access to customers in a store on a complementary basis along with purchases from the store. The store gives an Internet access code to the customer along with a qualifying purchase. The customer can then access the Internet through the store's WiFi hotspot by entering the access code when prompted for it. The access code grants a predetermined amount of Internet access time, based on the amount of the purchase or other terms specified by the store.
