I think the most important tech ever invented could be the Gutenberg Printer, iPad, or the IBM computer.

(Oh, and 'IBM Computer' is a computer invented by the IBM company.)

Printer: Gutenberg Printer, invented by Johannes Gensfleisch zur Laden zum Gutenberg in 1400s, was the first printer to print a book. (Except for our proud Jikji!)

The Gutenberg Bible!

iPad:
It's a clever new amazing device that leads the way after computers and desktop. 

And it's also really good.

IBM computer:
It was probably the most worldwide used computer.
