As far as performance and capability, it would be hard to beat the value proposition of the Tungsten E, but the lack of what should be a standard port for enterprise PDA management and expansion for PalmOS devices makes this unit too soft.
Zire 21: Vertical Use
PalmOne has upgraded its low-end Zire 21 with 8 MB of RAM and a 126-MHz TI OMAP processor. This Zire comes with a better selection of bundled applications as well. The screen size is 160x160 monochrome. Like the Tungsten E, the Zire 21 lacks a Universal Connector, so syncing and charging must be done using a standard USB cable and a separate AC charger. This unit will be too little for many enterprise purposes. However, for those applications that do work with the Zire 21 (and more will, given the memory and processor upgrade), the $99 price makes this an almost disposable unit. The Zire 21 is ideal for basic vertical applications, as well as the intended low-end consumer PIM market.
