Modern mobile phones market is a very dynamic and fast-paced environment. Almost every day we can witness the appearance of new models in the market; existing models become more sophisticated and offer more functionality. Nowadays it is almost impossible to surprise anyone with the built-in high quality camera, MP3 player or an organizer, although only several years ago it was a miracle, today it is a common standard. Now imagine, that all the huge mobile phones army is in command of the Smartphones - the Generals of mobile communication, their possibilities and potential are not commensurable with any usual mobile phone, no more restrictions and limits if you have a Smartphone.

So, what is a Smartphone? Taking into consideration that the whole history of "intellectual phones" is very short, they still do not have an exact definition, but it is possible to say, the Smartphone is a mobile phone and a pocket computer (PDA) multimedia hybrid. The Smartphone differs from a general Communicator mostly by size that is more compact and more expressed "telephone" orientation. Unlike usual mobile phones, Smartphones request more powerful phone facility control - Operating System (OS). The most popular OS that are used by major Smartphone manufacturers (Nokia, Motorola, Microsoft, Samsung, SonyEricsson) are Symbian OS, Windows Mobile OS, Palm OS and Linux.

Smartphone specifications list is almost endless and is limited only to user imagination and the owner's needs; the rest can be programmed in the OS and depends on the software installed on your Smartphone. Thus a Smartphone combines in itself all mobile communication standards (GSM/GPRS 900/1800, 3G), fax/modem communication, Internet navigation tools, e-mail protocols support (POP3, IMAP4 and SMTP), Office applications editors and, of course, all other standard features like organizer, polyphony, built-in MP3 player and a video camera. All Smartphones' undoubtedly characteristic is built-in Bluetooth or IrDA support for synchronization with other mobile devices or PCs. Using of own preinstalled OS considerably allows to expand Smartphones' area of use, that way a Smartphone can be anything from a usual mobile phone to the game console, GPS devices or optical human recognition system, it depends only on current market requirements and the price/quality parity.

Just like in usual mobile phone case, the process of choosing a Smartphone can be based on several simple principles:

• Smartphone sphere of use. For those who need it in their job, a Smartphone can offer a full access to Internet/Intranet Networks, editing/sending/receiving any types of documents, information interchange with other mobile devices. In case of the private use it is possible to navigate the Internet, create/edit audio/video clips, play-in multi-user games.
• Deciding which OS you want to use. Diverse OS offers different system interface and structure, which can help you solve some specific tasks.
• The presence of connection possibility other mobile devices and Internet/Intranet Networks. Usually a Smartphone has a Bluetooth or IrDA support, if both standards are supported - even better.
• The Price. The higher the price, the more intellectual can become your Smartphone, as a result the more it can do.

Popularity of smartphones is continuously growing due to their technological superiority over usual mobile phones, greater variety of new models and recent tendency to the price reduction. Smartphones have reached the lowest mark of $ 200-300 that corresponds to usual mobile phones of middle/high class price level. The choice is obvious. However, Smartphones are in the beginning of their way, it becomes already clear, that the future is for " Intellectual Phone".
