- 1st SmartPhone The IBM Simon Personal Communicator was an advanced cellular telephone for its time, created by a joint venture between IBM and BellSouth. Simon was first shown as a product concept in 1992[1] at COMDEX, in Las Vegas, Nevada. Launched in 1993[2] it combined the features of a mobile phone, a pager, a PDA, and a fax machine. After some delays it was sold by BellSouth in 1994 in 190 U.S. cities in 15 states and was originally priced at $899.[3] IBM Simon in charging station Besides a mobile phone, the major applications were a calendar, address book, world clock, calculator, note pad, e-mail, and games. It had no physical buttons to dial with. Instead customers used a touch-screen to select phone numbers with a finger or create facsimiles and memos with an optional stylus. Text was entered with either a unique on-screen "predictive" keyboard or QWERTY keyboard. The Simon had an optional PCMCIA memory card. The Simon smartphone appeared in the movie The Net.
- Nowadays nearly 15% of all mobile devices are already smartphones (this roughly represents a target population of nearly 600 million people). In the meantime an incredible variety of models and formats has been growing (and it doesn’t seem to stop!). There are literally hundreds of various device models sold around the world every year, which makes screen sizes far from being standard.
