I'm having a hard time finding a reason why I would buy this over the Raspberry Pi. Like others have said for this to be useful as a general purpose computer you need to buy add-on boards for video. Compare that to the RPi Zero which is $5 bucks and includes an HDMI port. You can easily add a USB ethernet or wifi adapter to the zero for under 4 bucks and have a real $9 computer.
Not to mention the CHIP uses an AllWinner processor which has a record of not playing well with open source and a history of security issues.
