Interesting idea.. I think what might even be more helpful is something that would count syllables for you, iambic pentameter, etc.

you want "i.e.", not "e.g."

i.e. = "id est" = "that is"

e.g. = "exempli gratia" = "example given" = "for example"

Architecture student here.

There is actually a large consumer base for a product exactly like this. I know many other architecture students that have spent more than the cost of a PandaBot (as well as months of hard work) building a RepRap printer to keep on their desk and use in studio. And we keep things (like models) far more fragile than this printer on our desks all the time.

Halfing the price of a comparable printer (MakerBot) is in fact a huge price difference (and therefore, a huge motivator for purchase) for people like students.
