I think that the difference between the take-up of PCs and the take-up of 3D printers by the average consumer will be that you could not go into a shop and buy software back in the 80s like you can go on line and buy stl files now for 3D printers. This factor could speed the take-up.

However, PCs in the home have a vastly greater number of functions than the single function 3D printer. What I mean is, PCs in the home are used for communication (emails, Facebook, Special Interest forums), education ( wordprocessing for class assignments), gaming, art, data storage etc, etc. I can't see many sons and daughters holed up in their bedrooms making 3D prints for hours on end as they do with PCs, iEverythings and such.

In regard to the Infograph: this is a well done presentation. I wonder what rock the people doing the survey were hiding under to only get 350 respondents to their survey. That number is not considered sufficient to produce reasonable survey results. The usual minimum number is around 600 to 750.
