Of course, for those savings there are some down-sides. The MK802 is from an unspecified manufacturer, and has a single core 1.5Ghz processor (as opposed to the dual-core FXI). Also, the HDMI is a connector, rather than a socket, so you’ll need to use a cable rather than just stick it into the back of a TV.
However, the MK802 comes with 512 MB of RAM, WiFi connectivity, and 4GB of internal storage. There is also an undetermined “3D Graphical processor” inside, but it does come with a plethora of cables and adapters for connectivity.
The device comes with Android preinstalled, although other platforms should also load onto it. And as mentioned, the device will set you back US $74 or 28 Omani Riyals.
