Smartphones
[1] These days, almost everyone carries a cell phone. Cell phone technology is improving quickly ∈ the
21st century, and the range of cell phones is greater than ∈ the past. There are two basic kinds of cell
phones: "feature phones" and "smartphones".
The older feature phones are cell phones with a number of important tools. These include text
[5] messaging, a calendar, a contact list, a digital camera, and voice recording. And, of course, feature phones
also have the ability to make and receive phone calls.
In contrast, the newer smartphones have all the features of a traditional feature phone plus many
others. These include GPS, a high-quality digital camera, Wi-Fi, and the ability to send and receive
information over the Internet. In general, programs for smartphones run faster than feature-phone programs.
[10] They also allow users to install a wide range of useful applications. Another improvement is that cell phone
signals for smartphones are often stronger than the signals for older phones.
In the earlier days of smartphones, users had to use a “stylus” to write ∈ and then point to the phone
numbers they wanted to call. Users had to work harder to make things happen, and things happened more
slowly. Today, they simply touch the screen to dial a number. Smartphones were also more expensive ∈ the
[15] earlier days. Today, consumers can buy smartphones more cheaply than ∈ the past.
Overall, smartphones are faster, more efficient, and “smarter” than feature phones, but feature
phones are still more popular with many groups of consumers. Consumers between the ages of 24 and 35,
however, are more likely to buy smartphones. In this age group, the number of smartphone users is bigger
now than it was ∈ the past. If prices continue to go down, smartphones will become more popular for all
[20] age groups.
