Seven Things to consider when choosing a PDA
To store in the early days, personal digital assistants (PDAs), not much more than glorified calculator with the ability to contact and brief notes. Now the line between PCs and personal digital assistant is blurred by the advanced capabilities of these devices small profit.
There are many brands and models to choose from the PDA market, and is the right design to suit individual needs can be a dizzying challenge. This techPlease take a look at seven basic things to be taken for the selection of a PDA in an attempt to simplify the process.
Software
The software on a PDA is to share as totally independent of your computer capable of, but in a location of files and resources between them is one of the most important comfort. The availability of software is a problem, but compatibility is another. Typically, a PDA will come with one of the two operating systems: Palm OS or Microsoft pocket pc, each with itsown, very different approaches to running one of these devices.
Palm OS is the modern version of the operating system, was found on some of the first PDAs, Palm Pilot. No longer just a dull, greyscale environment, which is a powerful Palm OS, with many software titles (including available as a download or product sold separately) to whatever you want to do on a PDA .
Microsoft pocket pc is the motto of family functioning WindowsSystem, and this similarity gives the millions of Windows users a comfortable environment for working with the transition to a PDA. The basic commands are the same, and all the software titles for a PDA with pocket pc, many of which are reduced "pocket" versions of what we see on a computer, such as Microsoft Word and Excel. Multimedia applications are a strong point of the 'pocket pc environment, with many titles developed to make these devices morecomfortable and versatile.
Applications must be made for both the operating system only for the same thing available, even if some tracks is not possible for others are available.
Speed
The speed of the processors in PDAs is increasing, and some older desktop computers are left in the dust of that little. Currently, most of the devices on the market operate at clock speeds of 300 MHz or higher, sometimes much higher. The HP iPAQ hx4700Sports an Intel processor at 624 MHz, which is also currently the processor in high-end Dell Axim X50v found

In general, faster processors on Pocket PC can be found, but this does not mean that Palm OS devices are slow. Many experts argue that the Palm OS operating system runs more efficiently, and may be able to get less system memory, which helpsSpeed competed.
Handheld applications have been optimized to run with less computing power, take less memory and a minimum amount of space, so both types of PDA should be able to manage well the typical tasks. Speed may be the main concern on a desktop PC, but the focus is a bit 'different portable devices, in which other features are far more important.
Connectivity
The possibility of connecting a PDA to a computer or other device canessential for full utilization of the functions, their full potential. Most now connect to a PC via usb, the basic form of data transfer to the device, but there are few wireless protocols are available, which on a handheld, so it can seem comfortable.
Infrared is a short-range protocol, which considers a PDA to be able to exchange data with another PDA with a PC compatible laptop or desktop computer. Many PDAs feature an infrared port, but not all computers. TheCommunications on this protocol are relatively slow, but for the transmission of basic data or synchronizing with a PC useful.
bluetooth is a protocol on the 2.4 GHz band, which has a greater range than infrared, but the speed is not so great. bluetooth can be used to transmit data from computers, but may also allow other devices to connect to a PDA. For example, a bluetooth PDA with a bluetooth enabled mobile phone can be connected in a position toAccess to the Internet via the phone as a wireless modem.
Wi-Fi, like on a typical computer, high speed wireless protocol (802.11x) that also in the band of 2.4 GHz Wi-Fi is not only compatible devices to exchange files, but the high-speed streaming media and web-surfing at home or at the numerous wireless "hot spots" the rise of public commercial settings.
Additional features & Accessories
Notenough to follow for PDA to keep nothing more serious business, like appointments and contact information. You must be able to multi-task, and most are now able to help, work and play with their owners. Many of these functions can be considered in some nice extras, but others may exist on their availability when choosing a PDA.
Many PDAs can now surf the Internet, streaming movies or playing video games thanks to the highest-resolution color display. Most now also a stereo audio processorfor listening to MP3s or other audio sources, and be able to double as a digital voice recorder too.
Other PDAs take the fun features to a whole new level. Some PDAs now double mobile phones. Or is that mobile phones that double as PDAs? Many phones have cameras now. PDAs like the Palm Zire 72 ([http://www.palmone.com/us/products/handhelds/zire72/index_gps.epl]) containing a digital camera to capture still images and video clips at decent resolutions.In another look at the Zire 72 shows another feature that has become popular in the PDA … GPS (Global Positioning System), the action and route planning will help during the trip.
Many PDAs also offer a wide range of additional add-on accessories to add ease of use and perhaps a bit 'flash on your PDA. For example, many manufacturers offer such things as spare batteries, extra stylus and update the care of skin. Other cool items can be a foldable keyboard,correctly with the PDA for easy typing, automobile charger so you can charge your handheld while driving

Extensibility
PDAs usually come with a basic amount of onboard memory for storing data and applications, but can be completed quite quickly. Most of these devices now also increases the slots that accept a type of flash memory for its ability to typical formats that are supported on PDAs: Compact Flash, SD, MMC or Memory Stick.
Flash memory is pretty cheap these days, but the choice of a PDA based on a format that can be useda good idea. An SD card that could be used, for example, between a PC, digital camera, move your MP3 player, PDA, and various multimedia applications and files between devices.
A PDA such as the HP iPAQ rz1715 offers an SD / MMC slot for expansion, while the Dell Axim X5 offers the convenience of flash memory slots that support most CompactFlash, SD and MMC.
Besides choosing the right format of flash memory for your PDA, you may needto examine the capacity of the chosen card. Although you may be able to purchase access to 2 GB of flash memory, for example, can not every PDA out. Check the manufacturer's specifications PDA, especially older models, to confirm that takes no maximum size, the card.
It also allows extra space slots for other devices can be used as well. GPS receivers are popular accessories for PDAs, and iswith different interfaces to play the slots on a PDA. Leadtek is one manufacturer offering both Compact Flash ([http://www.leadtek.com/gps/gps_9534_1.html]) and Secure Digital ([http://www.leadtek.com/gps/gps_9534_1.html]) for GPS receiver based. Another innovation from companies such as SanDisk, the memory and the combination of WiFi cards ([http://www.sandisk.com/retail/sd.asp?nav=mobile]). However, be sure to check compatibility with your current PDA, because they have some problems"Using the features of" extras.
Size
The overall size can vary from model to model, but generally the length and width of a PDA is in the range from 3 "x 5" cards will be. These values may vary slightly, and a difference of a few fractions of an inch, may be important for a user with specific space. For example, comparison of measurements of a Toshiba 830w (5.31 "by 3.03" by 0.65 "), to those of a Compaq Ipaq 3950 (4.54" x 3.00 "x 0.61 "), shows that the width and thickness are almost identical. But it can be the difference of more than ¾" in height a great thing when you try to fit in a briefcase, pocket, or even a pocket shirt.
The weight can be directly linked in terms of size, and perhaps another major sector to be taken into account. The weight of a typical PDA can (only a few grams to several hundred grams), so that is not obviously self-incrimination, armed with it. The difference between aModel and another may contain because of the variety and number of extra features, and can influence an individual's general requirements for functionality, the total weight.
Another important aspect when referring to the size, as it applies to PDAs is the image format. Large screens with higher resolutions, will serve as convenient as you can. Reference with the same two PDAs in this section, we see that sport a 830w Toshiba 4.0 "(480×640 resolution) screenwhile the Compaq iPAQ 3950, a 3.8 "(240×320 resolution has demonstrated). Therefore, the total size of Toshiba is a bit 'bigger, it makes good use of space, providing a large display capable of twice the resolution of Compaq.
Battery Life
Most PDAs are now with an integrated battery, the charge provided while connected to a base station or power supply. The most common form of rechargeable battery is lithium ion (Li-Ion) and a point of reference for a generalbattery capacity is provided in terms of mAh (milliampere hours). Although actual performance may vary between devices, and how they are used, a battery with higher mAh value is able to maintain a position higher and last longer between charges.
The general use of the device will obviously play a role, how long you keep the batteries, and it is difficult to give a number for sure. Manufacturers can create a character on a normal life between charges, but this iscloser to the occasional use, where it is inactive for much of the time. This number can be the battery life of up to several days to enter a tax, but under the operation at high intensity, battery life could be greatly reduced. A film of hearing, audio files, or games can make life in a drop of load from a few days to a few hours. The use of wireless networks and the backlight of the display are two other things that can have a serious impact on battery life on any PDAregardless of the type or quality of batteries included.
The best choice for information about the battery life is to seek independent reviews or comments on a PDA owner is of interest.
Final words
With all the options available PDAs are much more versatile than ever. Looking for a device with the flexibility to both business travelers and leisure useful not to be a daunting task when there are some important considerations identified at an early stage. GoodBalance of performance, size and capabilities should be easily reached, while paying attention as an adequate budget.
