Only the PC program… then the PDA!
Men love toys! Modern Multimedia PDAs is outstanding toys! Consequence: It occurs again and again that the mad Multimedia PDA is bought hastily and thought afterwards only about whether it fits also existing or planned agricultural applications.
Since there are hardly manufacturer-spreading solutions or completely independent agricultural applications for the minicomputer (except within the range of the surface oversize ASS ASS/S. top agrarian 9/2001), by the existing agricultural PC program in principle the associated manufacturer-specific Palm and/or application of pocket PCs given. Thus consider: Only the PC program… then associated PDA application and the fitting PDA!
Does pocket thePC displace the Palm?
Two, to each other not compatible systems dominate the market:
Palm (fig. left) with the associated operating system Palm OS (Palm organization system/current version 5.x) pocket PC (fig. right) with the special Windows operating system. The current version is Windows Mobile 5 |
Within the agricultural software range solutions Palm based first controlled the market. In the past years Palm lost however its dominating the market position as a quasi-monopolist in the PDA market. The competitive pocket PCs won more and more market shares in addition. With rising spreading of the pocket PCs also within the agricultural range increasingly applications for this TypC are offered. Some software houses develop their mobile applications in the meantime even parallel for both operating systems. In each case it recommends to inquire itself before the purchase, which hardware and which operating system versions are supported by the respective management often commodity on the PC. This is valid in particular with the purchase used or more again particularly “exclusive PDAs”. If their hardware equipment of the standard PDA deviates - for example a particularly high screen resolution - can Inkompatibilitäten with agricultural software the consequence be. With the direct hardware comparison by Palm and pocket PC it is to be considered that the Palm operating system and also the Palm programs are usually substantially more compact, as “hardware-hungry” Windows applications. The Palm comes thus with clearly less memory and clock frequencies to appropriate operating speeds. Still Palms are on the average more inexpensive, somewhat more compact and run more stably than the pocket PCs, which caught up however clearly and by the numerous hard and software provider the Palm more and more market shares to decrease.

Two operating system versions for pocket PCs
The mobile Windows platform caught up opposite Palm. That one marks also to the current offer at pocket PCs. A multiplicity of manufacturers offers the minicomputers in completely different price, achievement and equipment variants. The prices are enough from for instance from 220 to 500 euros. As consequence of the boom with passenger car navigation equipment the pocket PC is sold for example even over food Discounter regularly and finds always new groups of buyers. With the stronger spreading of the devices the agricultural software houses began to program their mobile applications also for the pocket PC to even only offer and/or new developments for the Windows PDAs. Current pocket PCs are offered with one of the following operating systems (an update is mostly not possible): Windows Mobile 2003 Second edition since March 2004 is Windows Mobile 2003 Second edition (Windows Mobile 2003SE) with the following improvements in relation to the previous version in the market:
Possibility the screen around 90° to turn improved pockets Internet Explorer (einspaltige representation) additionally to the usual 320_240 screen resolution, VGA with 640_480 and 240_240 and/or 480_480, for pocket PCs with keyboard support for Wi-Fi Protected ACCESS.
