Low cost tablets could double the number of netizens.  Devices like this one will make that possible.  Hardly flashy hardware, it's "good enough" for many applications.  At $20 or $40 or even $60, imagine what this will do to enable entrepreneurs of all kinds.  

At these prices, imagine how difficult it is for purpose-built device makers to compete.  POS terminals for example.  Add a secure acceptance device (it could cost more than the tablet) and you have a tool able to provide line of business capability, mobility, and payment acceptance.
