I think the price is not hard to achieve for an Android PC with mobile parts because the Ouya which is an Android game console cost only $99 with a controller, and the Gamestick also a Android game console cost $79 also with a controller. Controllers usually cost $50 while USB Keyboards can be bought for $10 if you buy generic brands.
There are also
Android Stick computers selling for $33 or less on Amazonwith similar specs, but no keyboard.
The Rasperry Pi only cost $35, and it can also run Android, but it just comes with a circuit board, and you need to buy the rest of the stuff.
A lot of Chinese brands like CoolShip also sell electronics at a cheaper price to better compete with American, Japanese, and Europeon brands because a lot of people just refuse to buy more expensive Chinese brands when they can get an American brand like HP, Dell, and others for the same price.
The Chinese Communist government gives favors to factories, innovative citizens, and job creators like CoolShip, so they pay less taxes, and get more government help by ways of loans, research and development, and support from the government unlike western countries like the US where the job creators like Microsoft, Google, Apple, GE, etc get heavily taxed sometimes to support government programs like public education, healthcare, wellfare, and social security.
CoolShip reached its Indiegogo funding goal of 10,000 USD by raising almost 14,000 USD, and you can still make a pledge for one in the next 10 days at

Indiegogo would of shut down this project if they think it is a scam since Indiegogo is a legal and real crowd-funding site like Kickstarter.
