I think the biggest influence of mobile phone is that,it changed the truth for time and space.
we usually think time is flowing slowly,just like how we move from on point to another,but with cell phone,you can reach anyone at anytime.there is no more space between people anymore.
what is also interesting is that,people now only can reach other,but they can also change the things far far away.for example,a doctor may not need to reach you to heal your sickness and introduce medicine to you to help you.
mobile phone is miracle:
1.Mobile phone can bend space,a person can be at two or even infinite location at one time.
2.Mobile phone can bend time,you can do infinite things in one minute,you can place orders,transfer information,even help others in a short time,which this time might be very long without the mobile phone.
so open your imagination,what a world would be like without time and space.
I feel I lived longer than anyone before the 20th century,because my time is much longer than theirs,and I don't even need to fly to get where I want,more than a super man.
