Just check out this Rainbow USB hub and you’ll realize what wonders color can do to an otherwise dreary device such as a USB hub. The device is not only distinctive but also well designed. Each USB port is a colorful plastic box wide enough for you to plug in big devices. But what hooked me is that it gives the functionality of a 4-port hub (plug-n-play, 2.0 compatible) in addition to being really flexible. How so? Well, each port is connected to the adjacent port in such a way that the ports can be arranged in a stack, tower, pyramid etc., depending on your liking. Definitely another one of those must-have USB gadgets on my list.
