That s why there are special challenges involved with luggable devices. Give your users a great application on a device that s convenient to use and carry and you may never hear about it. But others can be expanded through peripherals and add-on modules. Peripherals and expansion modules allow devices to morph into other things. PDAs can become cell phones.
Cell phones can become cameras or bar code readers.
And a new piece of hardware opens up the application opportunities considerably. For example, a PDA with a wireless interface makes for a great inventory tracking system but the application could be ten times as efficient and accurate with a bar code reader. Digital cameras present some unique application and service opportunities as well, and they don t all center on sending pictures to grandma. Not all wireless devices directly incorporate peripherals or include add-on strategies. In some instances, third parties have fashioned peripheral solutions around them anyway.
