Con Only one USB available for peripherals
There's only one USB port available for peripherals, which is a bit annoying considering how two USB ports is a minimum to have a keyboard and a mouse hooked up without having to use a powered USB hub.
Con Lack of a proper OpenGL driver
It sounds like the driver is possible, but the information is spread out over forums and GitHub.
Con Lack of support, Unstable USB 3,
Only Android with TV UI is available. It is almost unusable with a touchscreen display.
Community is somewhat helpful but is very small. The board developers do not participate in community discussions. No regular Android build available. Lack of accessories and project guidelines.
Con Power connector is not MicroUSB or MiniUSB
Can't use power banks as a power source because of that.
