The beta units were 600 euros, while the chipset is $87.
Meanwhile an Acer Aspire E 15 for $600 gives you a $297 CPU and $70 graphics card.
I guess there is some overhead because the beta was 10 units not a hundred thousand units, but still. You might as well get a Raspberry Pi and a portable screen and stick them in a box. It's half the price and you can use the components for other things after you get bored.
