Things are about to heat up in the dongle wars. Amazon has just announced that they have started to ship the first batch of orders of their Fire TV Stick, basically Fire TV shrunk down to an HDMI dongle size. The retailer claims that it is their fastest-selling device ever, and perhaps it shows. The Fire TV Stick is immediately out of stock, with inventories replenished by January 2015. Of course, you can still leave your order and they will be filled if and when the devices arrive.
