First SmartPhone :
People didnt start using the term
“smartphone” until 1995, but the first true smartphone actually made its
debut three years earlier in 1992. It was called the Simon Personal
Communicator, and it was created by IBM. The IBM Simon Personal
Communicator (simply known as IBM Simon) is a handheld, touchscreen PDA
designed and engineered by International Business Machines Corp. The IBM
Simon was the first phone with a touchscreen in 1992 — it’s also
referred as the first “smartphone,” though the term was not yet coined. A
few competitors came out in the early ’90s, but most mobile devices
with touchscreens were more like PDAs. IBM’s Simon was the first phone
to meld together the functions of a cell phone and a PDA, and it
launched with the price tag of $899 with a service contract.
Despite this, Simon suffered from a number of issues, such as reportedly
having a battery life of just one hour. It was also a bit of a flop,
with various repor spointing out that the device only spent six months
on the shelves, shifting around 50,000 units.
In addition to its ability to make and receive cellular phone calls,
Simon was also able to send and receive faxes, e-mails and cellular
pages. Simon featured many applications, including an address book,
calendar, appointment scheduler, calculator, world time clock,
electronic notepad, handwritten annotations, and standard and predictive
stylus input screen keyboards.
