Open source just means Arrington won't need to pay coders to write the software, and will get to enjoy discounts from people who have contacts to help build the hardware.
I did a research about this subject and it could be done... even with price around 200$.
They will face two big problems:
1) touch screen
- what type they would use? how it "lights"? weight?
2) battery
- capacity? POSITION of battery!
and few other problems such power supply (integrated?).
CPU, RAM, SSD are not problems, they are cheap and really easili intergrated, OS is not problem too (already seen such devices with Linux).
And the last thing is design... lets face it. It's important how it will look and feel when carrying. And I'm not talking about catching the right size of it (in my research A4 is too big and A5 is too small).
So lets see what will happen... I offered I will try to help them, what about you?
