Technology

I use various technologies every day. I am using cell phone most in technologies. The cell phone is used on mail, telephone, camera, and Internet, etc. The advantage of the cell phone is very light, and is convenient carry and walk. But, when cell phone have no more the battery because it is rechargeable. The technologythat I am not good is a personal computer. I reason that becouse used of cell phone had spread, personal computer did not use it on mail and Internet, etc.
I think that life became rich compared with old times by the technological improvement.
