It is increasingly difficult to define exactly what qualifies as a smartphone. Nearly all new mobile phones have some rudimentary PDA functionality such as phonebooks, calendars, and task lists. Furthermore, BREW and Java ME devices allow for the installation of additional applications but are still not considered smartphones. There are many BREW devices with PDA functionality, the ability to run third-party applications in native code and sporting displays as large as 240x320 pixels; yet they are not considered smartphones. The elusive definition seems loosely tied to the particular operating systems listed below.

The first smartphone was called Simon designed by IBM in 1992 and shown as a concept product at COMDEX. It was released to the public in 1993 and sold by BellSouth. Besides a mobile phone, it also contained a calendar, address book, world clock, calculator, note pad, e-mail, and games. Customers could also use a stylus to write directly on its screen to create facsimiles and memos.

As of 2004 smartphones are an increasingly large part of the mobile phone market. According to analyst house Canalys smart phone shipments increased over 100% from 2004Q2 to 2005Q2, with over twelve million devices shipped in the latter period. In a couple years, it is likely that most phones sold will be considered smart, except for disposable phones.

Most common operating systems are Symbian, Palm OS (developed by PalmSource), Windows Mobile (formerly known as Windows CE, and developed by Microsoft), BREW (technically a platform developed by Qualcomm), and Linux.
