Palm Os Software

When most of the other Palm OS vendors dropped out of the market, Palm rewrote their PIM applications and came out with a new internal architecture that was not fully compatible with Palm OS applications written for the earlier generation devices. We refer to the older devices as Legacy devices. Here is a list of specific devices which fall.
Treo 90—Palm OS 4.1H, can be updated to 4.1H3 which adds SDIO support; Treo 180—Palm OS 3.5.2H; Treo 180g—Palm OS 3.5.2H The Treo 180 with graffiti area, rather than a thumbboard.

Palm Computing

The company Palm Computing was founded by Jeff Hawkins in 1992 and Donna Dubinsky was appointed as CEO. At first Palm develops the applications software for numerous handheld models. Palm Computing can be defined as a pioneer in the market of mobile and cordless small computersWith the self developed operating system Palm OS® for handhelds it is possible to having permanently important data handily and mobile available. Palm OS works as a personal assistant for the information management. From more than 7,000 applications in April 2001 the number has increased to more than 18,000 in July 2003. The combination of Palm OS with a handheld makes the intuitive and simple operation possible at high battery runtime. Because Palm OS resides in a ROM, the hardware reset puts the PDA into the origin status, all modifications and after installed applications are removed from that battery buffered non-persistent memory. Palm OS has a flexible, open architecture, the maximum resolution on the monochrome LCD are only 160x160 pixels.
Palm was bought in June 1996 of U.S.-Robotics. The first Palm Pilot was released in March 1996. In May 1997 the 3Com Corp. acquire the company U.S. Robotics with Palm Computing. The Palm III organizer is introduced to the public in March 1998. Palm OS 3.x uses features of the AMX kernel of the company Kadak. Because of licence conditions only singletasking is possible for applications. To solve this restriction, Palm OS 5.x uses the own developed Kernel MCK with the ability of multitasking for applications.
Jeff Hawkins and Donna Dubinsky leave 3Com corporation in November 1998 and set up the company Handspring, Inc. which becomes a licensee of 3Coms Palm OS. In March 2000 the company Palm Inc. is founded by 3Com as an independent subsidiary firm, main field of enterprise is the development of Palm OS based PDA devices. The market share of Palm OS was 65 percent in 2000 (source: Gartner). Important business and technology partners are for example Handspring, IBM, Kyocera, Sony, Samsung and Symbol Technologies. Handheld models with DragonBall or ARM CPUs (supported since Palm OS 4.0) are the Palm IIIe, IIIx, IIIxe, IIIc, V, Vx and m100.
The foundation of the subsidiary Palm was completed successfully at the beginning of 2002. The company Palm was renamed in PalmSource (Inc.) in May 2002. Palm OS was ready for further device manufacturers for independently licensing. The device manufacturer Palm Solutions announced in June 2003 to take over the company Handspring. Palm had completed the take-over of Handspring in August 2003 and renamed for the area of hardware to PalmOne and for software and Palm OS to PalmSource. Mayn investor at PalmSource is Sony. PalmSource buys China MobileSoft (CMS) in January 2005.
Update July 2003: Till now, Palm OS was sold almost 30 million times, more than 260,000 developers support Palm OS and applications. New handheld models are the Zire 71, Tungsten C and Tungsten T with an ARM9 CPU.
The worldwide sales of PDA devices in quantities spread out as follows in comparison of the previous year to the 1st quarter 2004 (source: Gartner).
Palm OS fell from 49% (1Q03) to 41% (1Q04), Windows CE got itself of 37% by 3%, devices with RIM (Research In Motion) increased from 3% to 15%. Devices with Linux stayed approximately constantly with 2%, other operating systems fell from 9% to 2%.

The Palm computer had a sensitive display area which serves at the same time for the representation. By the key field the direct access to the calendar, adress book, task list and nbotices is possible. To install new programs (file format *.prc) a PC with installed Palm desktop software is required, which is used to install the programs about the Hotsync process. The synchronisation of the notes and dates for example between the PC and Palm happens the same time, the deinstallation of programs can be done directly in Palm OS.
