Well today’s mobile phones are all smart (almost). A smart phone typically is a phone which is suitable to people on the go or business people or corporate users.
They are people who are on the move and would want to use the Internet, Email and other productivity tools like Microsoft Office which they would normally use on their desktops or laptops. Smart phones / business phones offer seamless integration with desktops and laptops via USB or Bluetooth. You can synchronize data, email and contacts.
Another important feature in a business / smart phone is that it has a QWERTY keyboard and touch screen interface to make it easy to use. They will also have the ability to open documents like PDFs, DOCs, PPTs, etc.
