1967 Texas Instruments came up with a pocket calculator that was 1 kg heavy and could do the four basic ways of counting: multiply, adding, substract and deviding (spelling). It was probobly not the fastest one but hey...
So horray for the pocket calculator.
By the way I've got a Texas Instrument TI-86 Grafic calculator and that one is a really good one...

It looked like this:
The first handheld calculator. 
A paper tape was used insted of digital numbers.
The first "official" pocket calculator - Sinclair Executive, introduced in August 1972.

I have a TI84 because it was required for the math lessons. Now I don't know what to do about it.
