Buffalo has introduced the Reversi-hub.
Unlike normal USB devices which have a plastic piece which juts out such that users can only plug in when aligned with the port, the Reversi-hub has a thin piece of plastic which allows users to plug in the right side up or even upside down. In three models (3, 4, and 5 ports respectively) with four different colors, it is compatible with both Windows and Mac platforms.
The Reversi-Port USB Hub will be available in stores from November 2012 onwards:-
4 Port BSH4UD18: S$19.90
3 Port BSH3UD03 and 5 Port BSH5UD06: TBA
