The LifeDrive was a Palm OS-based handheld personal digital assistant device that was produced by PalmOne, a former incarnation of Palm, Inc. The device was PalmOne's first and only foray into the "Mobile Manager" device category. As its name suggests, Palm intended the LifeDrive to be capable of providing all the capabilities and data storage space that a user could possibly need during the course of the day, including contacts, calendar, music, images, video, and applications. At the time of release, the 4-gigabyte capacity that was chosen for this task could not be achieved using the flash memory used by most PDAs, while keeping the cost of the device low enough for consumer purchase. For this reason, a 4 GB microdrive hard disk drive was selected for the task. It featured a separate data partition that could be used as a portable disk drive. The LifeDrive featured Bluetooth and Wi-Fi connectivity, the first Palm handheld to feature both. The device came pre-loaded with eReader, Documents To Go, and WiFile software.

A mobile device is a computer small enough to hold and operate in the hand. Typically, any handheld computer device will have an LCD or OLED flatscreen interface, providing a touchscreen interface with digital buttons and keyboard or physical buttons along with a physical keyboard. Many such devices can connect to the Internet and interconnect with other devices such as car entertainment systems or headsets via Wi-Fi, Bluetooth, cellular networks or near field communication (NFC). Integrated cameras, the ability to place and receive voice and video telephone calls, video games, and Global Positioning System (GPS) capabilities are common. Power is typically provided by a lithium battery. Mobile devices may run mobile operating systems that allow third-party apps specialized for said capabilities to be installed and run.

The Franklin REX 5, was one of the Rex line of Personal Digital Assistants, each a PCMCIA PC card and thus the size of a credit card, built around a Toshiba microprocessor emulating a Zilog Z80. The REX firmware was written by Starfish Software, and the hardware was manufactured by Citizen Electronics. Earlier models in this line had almost no input possibilities except to download data when installed in a host computer or in a docking station; the Rex 5 added a sixth button and introduced a modal input method. Further, with 512 KB of RAM, the Rex 5 had twice the memory of the Rex-3.

The REX 6000 is an ultra-thin Personal Digital Assistant (PDA) produced by Xircom, and later Intel, from about 2000 to 2001. Its primary claim to fame is as "The world's smallest full-function PDA", due to its unusual physical configuration as a PC card Type-II card. The REX may be synchronized by inserting it in a host PC's PCMCIA/PC-card slot. Docking stations were manufactured for connection to hosts without PC card Type-II slots, which allows the REX to be connected via a USB or serial connection.

The Sharp Wizard is a series of electronic organizers released by Sharp Corporation. The first model was the OZ-7000 released in 1989, making it one of the first electronic organizers to be sold. The name OZ-7000 was used for the USA market, while in Europe the device was known as the IQ-7000.

The Linux Documentation Project considers the Zaurus series to be "true Linux PDAs" because their manufacturers install Linux-based operating systems on them by default. The name derives from the common suffix applied to the names of dinosaurs.

Smartglasses or smart glasses are wearable computer glasses that add information alongside or to what the wearer sees. Alternatively, smartglasses are sometimes defined as wearable computer glasses that are able to change their optical properties at runtime. Smart sunglasses which are programmed to change tint by electronic means are an example of the latter type of smartglasses.

A smartwatch is a wearable computer in the form of a watch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides for management and telemetry. While early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing, 2010s smartwatches have more general functionality closer to smartphones, including mobile apps, a mobile operating system and WiFi/Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth headset. Some models, called 'watch phones', have mobile cellular functionality like making calls.

Timex Datalink or Timex Data Link is a line of early smartwatches manufactured by Timex and is considered a wristwatch computer. It is the first watch capable of downloading information wirelessly from a computer. As the name implies, datalink watches are capable of data transfer through linking with a computer. The Datalink line was introduced in 1994 and it was co-developed with Microsoft as a wearable alternative to mainstream PDAs with additional attributes such as water resistance, that PDAs lacked, and easy programmability. The watch was demonstrated by Bill Gates on 21 June 1994 in a presentation where he downloaded information from a computer monitor using bars of light and then showed to the audience the downloaded appointments and other data. The early models included models 50, 70, 150 and model 150s. The model numbers indicated the approximate number of phone numbers that could be stored in the watch memory. These early models were, at the time of their introduction, the only watches to bear the Microsoft logo. The watches have been certified by NASA for space travel and have been used by astronauts and cosmonauts in space missions. There had been an evolution over the years as to the number and type of entries that can be stored in the various watch models as well as the mode of data transfer between computer and watch. At the time of its introduction the watch was considered high-tech.

A wearable computer, also known as a wearable or body-borne computer, is a computing device worn on the body.

The Yopy was the name of a series of Personal Digital Assistants (PDA) made by GMate Corporation, also used as a popular PDA Phone in Korea and based on the Linux operating system.
