I disagree, just for sitting on your ass (no mobility) this product has the potential to eat big screen's lunch. No more tv, multiple monitors etc... in a home. That alone may justify a big price tag.

if portable, then it becomes an ad platform in the wild ( say when shopping). Ad rev may subsidize it and lower the price even more.

Finally, there's an iris scanner. Govt LOVE that. Another way for it to be subsidized.
