It does look as though we simply cannot live without a Wi-Fi hotspot these days. Of course, there is always a data plan with which we can make use of, but why bother taking up the bandwidth of our own plan when there is a free line around somewhere? This is the reason why I love hostels when traveling – more often than not, the Internet there is a whole lot faster and more accommodating than forking out a bomb at luxurious hotels. Well, the $12.99 Hot Spot Color Changing Mug will surely let the world know that you live on two and two things alone – a good Wi-Fi hotspot, and a piping hot cup of java. Hot liquids in the mug will turn the Wi-Fi bars blue, now how about that?
