Not the only Bluetooth 4.0 dice on the market -- Scosche has a set as well -- Game Technologies' Dice+ ($40) is still pretty interesting. A single die can be used with a handful of games on your compatible iOS device. Roll the die, and the number that comes up will be communicated back to the iPad, iPhone, or iPod touch. Dice+ comes packaged with a micro-USB cable for recharging. A carrying bag is also included.
