Determine Your PDA Needs

Determine Your PDA Needs

All the latest and greatest features sound great, but what do you really want to do with your PDA? Before you start clicking through item listings, determine what you need out of a handheld device.

Contacts & calendaring

If you just want to keep a list of business / personal contacts and keep your schedule straight, you don't need a top-of-the-line PDA. An older Palm or Pocket PC with limited memory and a monochrome screen will work just fine.

Email & Internet

Send and receive email, browse websites, and organise your calendar and contacts with a more advanced Palm or Pocket PC . Communicate with other devices away from the computer with Bluetooth, Wi-Fi, or an IrDa port (infrared). Make sure the PDAs you look at support the features you desire most. You will need to sign up for service before using email and Internet features.*

Phone calls and more

A handful of PDA/cell phone combo devices, including the Palm Treo, HP iPaq , let you make calls, surf the Internet, instant message, email, and handle basic contact and calendar management. You will need to sign up for cell phone service before using cell phone features and Internet service before using Internet features.*

*Notes on service fees: Cell phone, data transfer (instant messaging and picture messaging), and Internet/email fees vary depending on your service provider, how much time you spend using a service, and the amount of data you send and receive each month. If you want cell phone service, expect to pay a monthly cell phone service fee as well as a monthly fee for Internet/email access.

Choose a PDA Operating System

Choose a PDA Operating System

Deciding between a Palm OS device and Pocket PC was once the most critical decision a person had to make when buying a PDA. Now manufacturers offer comparable features and pricing for Palms and Pocket PCs. Base your decision on personal preference. If you want advanced features and a comfortable keyboard, the T-Mobile Sidekick or RIM Blackberry may also work for you.

Palm

Palm devices run the Palm operating system and include software to help you keep track of contacts and appointments. Most come with third-party software to synch with your Outlook email, but you'll need additional third-party software to have it synch with other Microsoft Office applications.

If you're not addicted to Microsoft, recent Palm devices boast as many additional features as their Pocket PC counterparts. The streamlined operating system doesn't take a lot of memory to run, and you can get them with monochrome or colour screens.

The Palm devices you'll see most often from sellers include the Palm Tungsten, and Palm Zire. If you want a PDA with a built-in cell phone, look into the Palm Treo.

Pocket PC

Pocket PC handheld devices run a version of the Windows operating system. Older PDAs run Windows CE and newer devices run Windows Mobile. Pocket PCs come with Pocket PC versions of Microsoft Office applications including Pocket Word, Excel, PowerPoint, and Outlook, which integrate with your full desktop applications. They also come with Windows Media Player to play back audio and video files. If you want a PDA that immediately integrates with Microsoft Office applications, look into Pocket PCs such as the Casio Cassiopeia  HP iPaq

If you are comfortable with the Linux operating system, look into the Sharp Zaurus and make sure sellers specify Linux as the operating system for the device.

RIM Blackberry

Bluetooth-enabled RIM Blackberry devices include an organiser, browser, keyboard, and most include speakerphone. You can access your personal email with it or, if your IT department supports the technology, access your corporate email from a compatible Lotus Domino or Microsoft Exchange server.

Airtel offers service for  different Blackberry devices in India. Make sure the PDA you want works with the service you want to use. Sellers will usually include this information in an item description.

Symbian OST
The Symbian OS is primarily an OS for smartphones. The Symbian OS is used by some of the largest smart phone manufacturers such as Nokia, Sony – Ericsson, Samsung, LG etc. You can access email and run Microsoft Office applications like Word, PowerPoint and Excel applications. Symbian can be found on some of the most popular smart phones today such as the Nokia 9210i, 9500 and 9300, Sony Ericsson P900, P910i and the Sendo X.

Select Your PDA Memory Requirements

Select Your PDA Memory Requirements

In general, Palm OS devices use memory more efficiently than Pocket PC devices running Windows. But no matter which operating system you choose, the more you plan to do with your PDA, the more memory you'll need.

• 16 MB: 16MB is adequate to store contact information and perform basic calendaring.

• 32 MB: 32MB is required to run additional programs such as PDA versions of Microsoft Office applications.

• 64 MB: 64MB is recommended to play audio and view video files.

If you want to use your PDA to listen to music, store images, or play video, consider looking into a model with an external expansion slot. Expansion cards let you store information on the same type of CompactFlash, Secure Digital, or MultiMediaCard memory card you may already use in your digital camera or MP3 player.

Evaluate PDA Screen & Battery Options

Evaluate PDA Screen & Battery Options

PDAs can come with either a monochrome or color screen. Bright and colorful screens enhance your PDA user-experience, but the larger and brighter your screen, the more battery power you use. There are a few ways to help you extend your PDA’s battery life:

• If you buy an older PDA that runs on AAA batteries, make sure it has a monochrome screen.

• A battery usually lasts 2 to 10 hours on a single charge. If you want to get the best battery life, don't use the brightest screen setting.

If you buy a later model PDA that runs on rechargeable batteries, and you want to use the brightest screen setting, look into models that have removable batteries and keep a spare battery handy.
