Knowing that I've an iPhone, my friend asked me what's the difference between a smartphone and a normal phone when a normal phone can do everything a smartphone can.
Smartphone can play video, so can a normal phone.
Smartphone can play music, so can a normal phone.
Both phones can install programs, apps and games.
Both phones can take photo and video (in fact, her normal phone is 8mp with flash!)
Both phones have large memory (by having a large memory card, her phone is 64GB, larger than iPhone 32GB)
Both phones can surf internet, MSN and emails.
So what's the difference?
Why is smartphone more powerful?
