The importance of the PC in my job can be described as essential, because all my work is done in digital formats, this means i don't work with physical documents, i work with digital documents, digital mails, source codes of programs, etc.
My favorite piece of technology is the cell phone of course, a smartphone specifically, because it gives me a total control about my personal issues like make calls, read e-mails, visit my favorite sites on the Internet, look at my pictures, listen music, watch videos, etc.
There are applications that can be downloaded from the on-line Market, these applications can be used to connect to Skype to call someone, or chat whith someone.
Android is the operating system that using my SmartPhone, this is a great advantage because you can download a lot of free applications.
Definitely my SmartPhone became a key piece of technology very difficult to leave.
