It seems like everything's got Wi-Fi these days: smartphones, tablets, weather monitors, baby monitors--even children's toys. More than we'd like to admit it, if it weren't for Wi-Fi, we might not know what's going on at all times of the day.
But there are other uses for Wi-Fi than merely surfing the internet. More specifically, Wi-Fi can be used to stream movies, control your Mac and--hey!--get you on the internet when you're in a far away country. This week, we highlighted three free apps that stream movies between your Macs, let you control iTunes or Apple TV with your iOS device and find a Wi-Fi hotspot in Sweden without even connecting to the internet.
