I perhaps do not need to explain to you what a smartphone is. You already know what it is and you should also know that it is some expensive. In the time of economic recession, many people would not want to spend money and smartphones should not have sold well. However, the opposite thing has happened.

Smartphone shipments were up 4.2% globally in the third quarter and reached a record total for a quarter despite the poor economy, market research firm IDC said today.

Smartphone vendors shipped 43.3 million smartphones, such as the iPhone, in the third quarter, up 4.2% over the 41.5 million shipped in third quarter of 2008, IDC said.

I am some surprised with this report but it is perhaps natural that people now expect much more from their phones than just talking and sending SMS.
