The Orange Pi One features an Allwinner H3 1.2 GHz quad-core ARM Cortex-A7 processor, ARM Mali-400MP2 graphics, 512MB of RAM, and a microSD card slot for storage.
It has HDMI output, 10/100 Ethernet support, a USB 2.0 port, a micro USB port, a 40-pin Raspberry Pi-compatible header, a camera interface, and a few GPIO pins.
It’s available for order one from AliExpress. Note that shipping to the US brings the total price to $14… which is still not a lot of money for a computer.
This does look like a good computer for $14 including shipping.
