HeavyJob/Pocket is designed to run on Palm™ OS 3.5 and higher. Certain manufactures and certain devices have introduced small variations in to the Operating System such that although the devices are officially Palm™ OS 3.5 or higher, HeavyJob/Pocket will perform better on some than others. We have successfully tested HeavyJob/Pocket version P4.1 on the following handheld devices. For optimal performance, we recommend that you use one of these models: From Palm, Inc.: m515 Zire™ 21 Zire™ 31 Zire™ 71 Zire™ 72 Z22 Tungsten™ T Tungsten™ T2 Tungsten™ E Tungsten™ E2 Tungsten™ T5 Tungsten™ T|X Treo™ 650 From Kyocera™: Kyocera™ 7135 Smartphone. We do not recommend the following: All Sony™ PDA's. Sony™ takes liberties with the Palm™ OS which cause problems for HeavyJob/Pocket. Since Sony™ has exited the U.S. market, you are unlikely to view them as a candidate supplier anyway. Tungsten™ T3 from Palm™. This device has an expanded screen that handles input as well the normal display. We found several glitches in this new display while running HeavyJob/Pocket, and therefore do not recommend it. But these issues were not fatal, so if you already have a T3, you can certainly try it. Points to keep in mind when selecting a handheld for HeavyJob Pocket Memory requirements are modest. HeavyJob/Pocket requires only 640 kB. After loading it up with lots of setups and transactions for three jobs, memory usage increases to no more than 750 kB. All current PDA's have at least 8mB of memory. Color is not important. HeavyJob/Pocket uses color only for its cosmetic effect. You will not miss any functionality when using a grayscale device. Processor speed is not important. All Palm™ devices released since the m500 series have plenty of processing power for HeavyJob/Pocket. Keep with one manufacturer. Be aware that you are creating a standard for your company. Different vendors offer slightly different versions of the Palm OS and HotSync software, which may be incompatible. Note that we recommend devices from Palm, Inc. Ruggedness. None of the standard Palm™ OS handholds is built for the abuse they will see out in the field. Metal cases are an obvious solution, although they can be cumbersome. Our recommendation is to buy inexpensive devices, and be ready to replace them when they fail. We have deliberately written HeavyJob/Pocket to run on the slowest, low-memory, gray-scale machines, just to keep replacement costs low. If you want to use HeavyJob/Pocket E-mail The program is able to create an e-mail of your time cards that are then sent wirelessly to HeavyJob/Manager. This feature requires that the (free) Eudora E-mail client be installed on the handheld. It does not use the VersaMail included with current Palm™ devices. The Eudora client is part of the Eudora EIS package available for free download from www.Eudora.com. In order to send e-mail, you must somehow connect your handheld to the internet. Older Palm™ devices, such as the Zire™ 71 and Tungsten™ T2 have a Universal Connector into which you can plug a cable that connects to the PDA to a cell phone. We have successfully tested this E-mail creation and transmission from a Tungsten™ T2 and Zire™ 71 through a Nextel™ i1000plus phone using connection cables purchased from www.gomadic.com. Unfortunately, Palm™ has gone to either mini-USB or Multi-Connectors, neither of which can be used for simple serial connection to a phone. Palm™ touts Bluetooth as a new way to communicate with your cell phone, but this new technology is still too unsettled to be of use for most of our customers. Therefore, if you are looking to buy new devices and plan on using HeavyJob/Pocket E-mail, we recommend you use PDA/phone integrated solution like the Treo™ 650. Conclusion We think the lowest cost Zire™ models ( Zire 21, Zire 31, and Z22) make a lot of sense. They are inexpensive, have adequately powered processors, and in the case of the Zire 21, this grayscale screen is no problem with HeavyJob/Pocket. For customers that need e-mail connectivity, we recommend the Treo 650. This document was updated December 15, 2005.
