"The typical 2015 USAmerican/other developed state citizen is using what in 1997 we'd have recognized as an NC (Network Computer), while the typical third world citizen is using a more complex, more expensive, and less reliable personal computer (something similar to what many 1997 users had sitting on their desks).
Though there's a flood of 'free' low end NCs available to choose from now, most any premium NC actually purchased by a user in 2015 can be upgraded to awesome workstation capabilities relatively easily. Elements involved may or may not include something similar to having cable TV installed in one's 1997 home, as well as switching out a smaller monitor for a larger one, and perhaps plugging in a more advanced interface device like a digitizing pad.
Personal computers as we knew them in 1997 are no longer being manufactured in significant numbers in the developed nations; instead, the old style PCs (or the form factor we were familiar with in 1997-1998) are purchased for scrap in nations like USAmerica and then resold in third world countries to the poor.
Why aren't NCs displacing PCs in even the less developed nations too? Because many poorer nations in 2015 still don't enjoy an adequate telecommunications infrastructure to support NCs; therefore they need systems that may also function as standalones. Too, even in poor states which do possess a sufficient infrastructure, telecommunications fees are often prohibitively expensive for practical NC use. The bottomline is that the developed states' old PCs trickle down to (or are built for) third world citizens as the more fortunate in the developed states tend to utilize the entire internet as their platform, rather than a single, limited desktop machine."
