The Palm Treo was a line of smartphones originally developed by Handspring, which was bought by Palm, Inc. They were then manufactured and maintained by Palm, Inc. Treos had a number of integrated features such as the ability to check the calendar while talking on the phone, dial directly from a list of contacts, and send email messages. The most recent models include a built-in camera. Traditionally, Treos run Palm OS which allows synchronization with both Mac OS X and Microsoft Windows, but newer models also have editions that run Windows Mobile. Wikipedia [ - ]
