The early history smartphone

Today's technology revolution really became part of the largest contribution in the change in this world alone, Let us try to imagine how people used to write just about to write on a rock, has now developed into an e-reader such as iPad and various other electronic products. Or for example, once the wireless communication is to use smoke, has now turned into a mobile phone. Humans are creative, and this is proof positive that human beings are special.

But did you know, if you currently hold your gadgets like the iPhone, handhpone nokia, blackberry or other, that all these gadgets terinovasi of a smartphone named Simon? Yes ..., this is the first smartphone in the world created by IBM as a smartphone and was named Simon pesonal communicator. Together with its partner, BellSouth, IBM created the integration between the mobilephone, pagers, PDAs and fax machine. Simon's first model of the gadget was first shown in 1992, and sold to the general there in 1993 with a price of $ 899.

In addition to the above features, Simon Personal Communicator also comes with features such as calendar, address book, world clock, notepad, email and of course games. Even Simon gadget is already air-touch screen and has buttons querty. Not great, but unfortunately this time its size was about the size of bricks hehehe. So still very hard to carry on, even chargenya was still the size of a small picture book. It is conceivable hard to bring the gadgets and at the same chargeenya

Wireles Sensors
