The palmOne Tungsten E is a handheld Personal Digital Assistant (PDA). It runs the PalmSource Palm Operating System and was originally released in 2003 with version 5.2.1 of the OS, and was designed to replace the m515. At an average price of $199.00 USD, it is considered to be an entry-level PDA.
The case is plastic with a polished aluminum finish. Below the screen are 4 (four) application buttons used to quickly launch frequently used programs, and a navigation button. There is a slot on the right side of the case that holds the stylus. The expansion slot, for SD / MMC memory cards, is on the top of the device.
The Tungsten E has a 2.5 X 2.5 inch (320X320 pixel) 65,000+ color Transflective screen, which is considered to be a high quality screen for an entry-level device. The screen is easily readable indoors, but can be difficult to see outdoors, which is common for color LCD screens.
The battery is a rechargeable Lithium ion battery that is not user replaceable (unless the user opens the PDA and uses a soldering iron on the leads that attach the battery to the circuit board).
The memory expansion slot accepts Secure Digital memory cards or Multi Media Card expansion cards. These memory expansion cards are designed to allow the user to add additional memory as needed for files of many different types, such as MP3 audio files, video files, eBooks and other documents.
Size and Weight
The Tungsten E has a 5-way navigation button that allows the user to scroll up, down, left, right and select items on screen. Some users have had issues scrolling down with the 5-way navigation on this model.
There is a standard stereo headphone jack to listen to music or other audio files, as well as a tiny speaker used to play alarm sounds and music files. But because of the speakers' tiny size, most users opt to use the headphone jack to listen through headphones.
