Specs Explained

Handheld Specs Explained :

Not every handheld will suit every user, nor will every feature be applicable to every handheld. The features detailed here are meant to inform - not persuade - you while you decide which handheld to buy.

Size, weight, and form factor. Portability and design are important. After the thrill of a new device wears off, will you still want to cart it around with you?

Operating system. Remember that along with the user interface, the OS is the most important factor in terms of upgrades, application and utility support, and host/companion interaction, including synchronization and shared data.

Memory storage for applications and data. The amount of memory you need depends on the OS, the applications loaded, and the amount and type of data you intend to store. Check whether you can add memory via expansion cards, which significantly add to a unit's productivity and entertainment capabilities.

	Palm OS devices. 2MB RAM is the minimum; 8MB is the norm; 16MB is common.
	Windows CE devices. 6MB RAM is the minimum for recent units; 32MB is the norm.

Expansion. The more capabilities your handheld has, the broader its usefulness. Consider:

	the types of slots (i.e., Secure Digital, CompactFlash, MultiMedia Card, Memory Stick, PC Card)—many devices now have accessory jackets or sleeves that will accept removable media,
	connectivity or I/O ports, including a Bluetooth radio for serial wireless connectivity,
	the availability of accessories, and
	compatibility with other devices for sharing information with colleagues.

Communications ports. Handhelds are designed to support communication with other devices (such as PCs, other handhelds, printers, GPS devices, and digital phones) via serial and USB ports, cables, infrared, and wireless services.

Docking cradle. Check whether the docking cradle can be used as a battery charger--and whether there is a travel cable, so you don't have to carry the bulky cradle. Ideally, a travel cable is provided as part of the standard bundle and does not have to be purchased as an accessory.

Display. If you can't see the display, you can't use it. Consider:

	Monochrome or color. Color isn't just for looks; it can enhance productivity.
	Resolution. The higher the better.
	Indoor and outdoor visibility. Think about where you'll be using the device, and be sure you'll be able to view it easily in that environment.
	Backlighting and contrast adjustments. Are they present and easy to use?

Audio/Video. Audio features are particularly important if you plan to use your handheld as an entertainment device. Consider:

	Microphone. For voice recording and voice command as well as control of applications.
	Speakers. Monaural or stereo.
	Headset jack. Usually stereo.
	Music formats. Can the device play MP3? WMA? Other formats? Does it support Digital Rights Management?
	Screen resolution and color depth. If you want to display digital images on your handheld, the greater the resolution and color depth the better.

Data input. Will you use the device only to read and reference information, or will you write long memos? Remember:

	Character recognition is good for short notes at best.
	Standard keyboards are necessary for extensive input. A notebook keyboard is best.
	Virtual keyboards are convenient when you can't remember the shorthand symbol that the character recognition software requires, but don't assume they're as good as physical keyboards.
	Handwriting recognition doesn't always work as smoothly as character recognition. Try it before you entrust your time and productivity to a new device.
	Voice recording is fine for quick memos and limited command and control. Voice recognition for text entry requires more power than today's handhelds support.
	Infrared beaming is great for transferring data between handhelds or from a handheld to a printer. Bluetooth is increasingly a technology used for the same purpose.
	If you're merely transporting and referring to data, entering information on a PC and then transferring it provides the best of both platforms.

Battery. Don't underestimate or overestimate the power you'll need. Consider:

	Backup. Know whether or not you'll lose data and applications if the device's battery runs out of power. In some devices, you can protect data and applications by storing them in ROM.
	Battery type. Lithium polymer lasts the longest, followed by lithium ion, nickel hydride, and nickel cadmium.
	Rated life. Advertised ratings are generally accurate, unless you use the device constantly, with the brightness cranked all the way up.
	Recharging. Charging the battery shouldn't take more than 1 hour for each hour of use.
	Support for multiple types. If your battery runs out, can you use double-A alkaline batteries in an emergency?

PC integration. Find out how easy it is to synchronize your PIM and application data between your PC and handheld. Does the handheld come with desktop applications to aid integration? Can you use it with more than one PC?

Hardware controls. User interface and controls are a matter of personal preference, but buttons, jog dials, and wheels should be easy to find and use. Are there too many or too few? Is the device as easy for left-handed users to operate as for right-handed users? What functions can you perform one-handed? For example, can you look up a contact or make a phone call?

Stylus. The stylus should be comfortable to use and easily stored in the device. Can you buy extras from the manufacturer's Web site, or better yet, are they included in the box?

Software. Without it, your handheld is useless. The included software can more than offset a price differential between handhelds, if the included programs are useful to you. Check out what software is:

	standard with the OS,
	preloaded in ROM,
	bundled on a CD-ROM,
	downloadable for free from the manufacturer's Web site,
	Web-based services such as synchronization, or
	available from third-party manufacturers.

Accessories. The more, the better. Look for a wide range of accessories, including cases, cameras, MP3 players, GPS devices, modems, cables, battery packs, chargers, and clothing with special pockets for handhelds, from a number of different manufacturers. If you travel frequently on business, see whether you can get accessories shipped to a hotel overnight. Can you easily find accessories in office superstores? Before you purchase a device, add up the total cost with all desired accessories.

Alerts. Check out the various message and appointment or reminder alert modes available. You'll find various combinations of flashing LED, vibrating, audible, and on-screen visual alerts in handheld devices. Some devices let you customize LED lights and audible tones. Look for easy access to a control for switching from an audible to a vibrating alert when you need to be considerate of those around you.

Customization. If you like an individual look, buy a handheld with personalization features such as colored case covers, colored trim or styli, software skins, a range of fonts, and screen view format and color options.

Appearance. Some handhelds look cool; others look like brick slices. Enough choices are out there that you should be able to find one that fits your own personal style.

Protection. How easy is it to restore your data from a backup if your handheld is lost, broken, or stolen? Handheld operating systems differ greatly in their built-in security features, with varying amounts of emphasis on enterprise-level security, prevention of unauthorized access, and securing applications and data.

Warranties. If you're tough on your stuff, or if you travel a lot, look for extended coverage and consider getting insurance against screen damage.

User Support. Some OS developers and device manufacturers offer Web-based user groups, newsletters, and tips and software announcements to help you get the most from your device. These offerings are typically free and informative.
