Review: Treo 755p
For people who are not Palm OS users, the platform creates some initial confusion. Most users expect some sort of home or status screen on their phone, but the Palm OS does not have one. There are two default screens on the Treo 755p, the main application menu (reached by pressing the home key) or the phone dialer (which is accessed with the phone key).
The phone dialer is the closest the 755p comes to a home screen in that it can be customized to display a picture instead of a gigantic numeric keypad on the screen. It does not have plugins that can display specifics about missed events or, say, upcoming appointments like other smartphones - or even newer feature phones. The dialer also has an application launcher that eliminates the need to visit the main menu.
Palm OS is much more reliant on the the touch screen than other modern smartphones, which may lead to some confusion for new users. There are no soft keys to press, which is frustrating and confusing at first. All applications had a fairly consistent navigation setup, so after you've had some time to familiarize yourself with how things work, they are easy to use.
Navigation is definitely not optimized for one-handed use; the Palm OS still shows its PDA roots with buttons all over the screen and its reliance on a stylus. Application menus remain hidden until you tap the title bar or hit the menu key in the lower right hand corner, and once revealed work much like on a PC. Although you can navigate the menus and all the on-screen buttons and boxes using the D-pad, it often required scrolling through so many choices that we found just using our thumb to be a much faster solution.
