Accessory maker XtremeMac, showing at CES on the occasion of its 10th anniversary in the market, has taken the wraps off two new products today -- a lightweight, portable Bluetooth stereo speaker that also features a line-in jack for other music players, and a line of multi-device iOS charging docks that rely on the slim design of iOS products and which offer a full 10 watts in each port, with one model offering up to five charging slots.
