Universal Device
First mobile handsets were really big and heavy. With the development of mobile technologies their size was diminished greatly. Now the smallest mobile phone in the world weighs only 40 grams. The latest models are equipped with powerful accumulators and are still portable and small. Most of them can be charged through USB wire.
Mobile phones often have features beyond sending text messages and making voice calls, including Internet browsing, playing music (MP3 files), recording, personal organiser functions, e-mail, instant messaging, built-in cameras and camcorders, ringtones, games, radio, Push-to-Talk (PTT), infrared and Bluetooth connectivity, call registers, ability to watch streaming video or download video for later viewing, video calling and serve as a wireless modem for a PC, and soon will also serve as a console of sorts to online games and other high quality games. The mobile TV is developing and replacing common television. Some models have all the functions of pocket computers. They have the same software and functions. However, social surveys show that most of the functions are not used by the consumers. Most of them are not using mobile media or games-on-the-go.
Mobile phone is the universal soldier of our life. At the time that PC is the most powerful electronic device, mobile phone is the most popular one. We have it with us all the time. Some people have already succeeded in replacing PC by their handset.
