How many doors has “replaced” the USB?
In 18 year career, that’s all the doors that we do not have on our PC (or Mac).
Honestly, the first time I saw a USB port seemed to me the most useless thing in the world. Why would I buy a USB mouse, when those with the much more common PS / 2 connector cost much less?
I still think I was right, on the other hand, the only devices that could connect to the USB port was not just the mouse. Today, after years away, we can say that the USB has been one of those inventions that have really made history.
