Ford changed a few models to OAT, then backed away from it. VW, Audi, and Porsche are OAT users, too, but most others have resisted. Instead of OAT, most new cars now use a hybrid antifreeze that's formulated with both OAT and the silicate inhibitors from green (Japanese hybrids have different inhibitors). It comes in too many colors to pretend this type is color-coded.
Previously the USB port on the back of the device was locked down and couldn't be used for storage devices, but thanks to the recent updates, additional storage space can easily be added via a USB flash drive. Note that this update is for the Fire TV box only.
Fire TV Stick [edit]. On November 19, 2014, Amazon released a smaller version of the Fire TV called the Fire TV Stick. It is a HDMI-port plug-in device that replicates much of the functionality of the larger Fire TV. Its hardware is slightly different, it has 1 GB of RAM, 8 GB of storage, weighs 0.9 oz. (25.1g) and the CPU is slower.
