Z22 (handheld)
The Z22 was one of the first of Palm, Inc.'s handhelds to be released under the new "Palm" brand, and the first to be released without the "Zire" moniker. Released on October 12, 2005, it replaced the monochrome Zire 21, and was priced at $99 USD. The Palm Z22 featured Palm OS Garnet 5.4.9 and a 200 MHz processor. The Z22 runs on a standard li-ion battery that had a life of about 8 hours depending on its function.
Designed to be attractive to first-time users, the unit lacks frills such as an external memory slot, but has the capability of trickle-charging through the USB interface when connected to a PC (so the wall-socket charger can be left at home), and the NVFS, also known as NVRAM, means that the unit does not lose data even if the battery power runs out.
