Palm Zire & Palm Zire 21
The Palm Zire and Palm Zire 21 are inexpensive and are differentiated from the rest of Palm's line by having monochrome screens without backlighting, having only two quickbuttons instead of four, and a traditional up/down navigation button instead of a 5-Way Navigator, though both of these entry-level models are lightweight (3.8oz or 108g), sporting a white front with a matté gray plastic back.
The Zire, released in the fourth quarter of 2002 (also known as the m150), is the handheld responsible for starting the value-conscious handheld craze. It sported only 2MB On-Handheld RAM, a 16 MHz Motorola DragonBall EZ processor, and Palm OS 4.1.x. The Zire was superseded by the Zire 21 at the release of the "First Breed of PIM Plus Handhelds" on fourth quarter 2003.
The Zire 21, released at the same time as the Tungsten T3 and Tungsten E, sported an improved PIM suite (known as the Palm PIM Plus), a 126 MHz TI OMAP311 ARM-Compliant Processor, 8MB On-Handheld RAM, and Palm OS 5.2.1.
Neither the Zire nor the Zire 21 had SD/SDIO/MMC expansion, which was vehemently shunned by venerable handheld aficionados. As of August 2005, both of these handhelds have been discontinued, making the Palm Zire 31 the entry-level Palm-branded PDA citing a strong demand for color.
The zire 21 is capable of displaying pdf files using the free Adobe Reader for palm OS version 3. Like most palm handhelds, text from the pdf file can be copied and pasted into other applications such as memo pad, greatly enhancing the utility of this cheap device. It is capable of, in effect, acting as a portable word processor, albeit a very basic one.
Famous quotes containing the word palm:
“The oft-repeated Roman story is written in still legible characters in every quarter of the Old World, and but today, perchance, a new coin is dug up whose inscription repeats and confirms their fame. Some Judæa Capta, with a woman mourning under a palm tree, with silent argument and demonstration confirms the pages of history.”
—Henry David Thoreau (18171862)
