My favorite piece of Technology

Well, I'm not very skilled in technology stuff, but with the time I have learned that is a very important sphere in the modern life, because make life much more easier and quick in all aspects so you have to be trained to discover all the posibilities that the technology could offer you.
The device with a I started to understand all this world is my cellphone, a Samsung Galaxy i5500. Is a Smartphone which have a operating system, Android, so you can extend the funcionality of the device with different applications or "apps". This apps could be different kinds of games, or could be somethings so useful like an English-Spanish traductor. Also you can connect with social networks like facebook or twitter or you just can listen music or radio.
I got this device since one year ago, when I saved money to buy a cellphone which I could see my e-mail. In that time I considered not necesary a smarthphone but I just let myself go by this cellphone.
I use this device all time, seven days a week. Well I have to say it, I'm a little slave of this device, this is one of the consecuence of technology I belive.
