My last three devices

Technological change is seen as a social process which is constant changed with the cultural crises, political institutions or marketing direction. Nowadays,  the technology and human life are inseparable.

My last three devices as shown below:1) Iphone 4 with 16 GB,  I got it when I was first year in the Assumption University as a gift for my family. Here are some weakness of iphone4:

    Firstly, for lack of space, the multimedia messaging service and photos is really limitted.
    Secondly, for low quality of pixel. The colour is very far away from the original object and the front-facing camera is not clear when i used at the dark conditions.
    Later,  I gave it for my grandmother.

2) Adaptor plug, I got it last year in China. And my friend did not take away the plug when she graduated.Therefore, I keep them at my dormitory now.

3) Galaxy note 2 which is a smartphone that I bought.  Unfortunately, its screen was broken by myself, and the hands-free ear piece was also broken. However, it still can make or receive calls.
