Handhelds & Tablets
Handhelds & Tablets
Handheld computers are the offspring of early personal electronic organizers with calendars and address lists. Organizers, in turn, had been inspired by earlier electronic handheld calculators such as the Busicom “Handy.”
Tablets—with roots in both handhelds and laptops—usually have a touch or pen-operated screen. Initially successful mostly in specialized markets, such as warehouse management, they have moved into the mainstream.
The Busicom was one of the very first truly pocket-sized electronic calculators. These brought together all the needed components for later handheld computers; processor, display, keys, battery, and memory.View Artifact Detail

Handhelds: Defining Their Role
Full-sized portable computers always had a clear and general purpose: being a desktop computer on the go. But general-purpose handhelds were initially too limited for anything but niche markets such as inventory management.
Handhelds specialized for a particular function—such as calendar, address book, or cookbook—were more successful.
The Panasonic/Quasar Hand-Held Computers offered a full line of miniature peripherals, including a printer, modem, video-out adapter, extra memory modules and more. All fit in a single briefcase.View Artifact Detail
