[0560] Note that differences between settings in the portable mode and those in the console mode are not limited to those described above. For example, in other embodiments, the information processing device 1 may impose only one of the limitations (a) and (b) described above in the portable mode. For example, in other embodiments, the information processing system may use different communication methods for the communication with external devices via a network (e.g., the Internet) (in other words, may switch between different communication methods) in the portable mode and in the console mode. For example, consider a case in which a predetermined network connection device is connected to the cradle 5, the predetermined network connection device having a function of connecting to and communicating with the network. In such a case, in the portable mode, the information processing device 1 may communicate with the network using the network communication section 82. On the other hand, in the console mode, the information processing device 1 may communicate with the network via the cradle 5 and the network connection device.
