It is said that an abacus was the 1st computer..
The first smartphone was a fruit... but not an APPLE, a BLACKBERRY (well actually no, probably a Palm or Windows Mobile device..or maybe even a Psion - believe those had a SIM slot - or a Sony Vaio).
Nintendo made the first popular portable computer...???
But WALKMAN was there before the GAME BOY...
A handheld abacus was the 1st popular portable computer? Casio digital calculator?
