In Pictures: Pocket marvels - 40 years of handheld computers

From the first pocket scientific calculator through '80s organisers to today's tablets, check out 15 ingenious devices that have driven the handheld computing revolution.

2004: OQO Model 01

PDAs weren't powerful enough. Hybrid laptop/tablet PCs were too big. If only there were some middle ground.

Oh, there was: OQO's $1,500 Model 01, a paperback book-sized tablet PC with a slide-out backlit keyboard. The svelte 5-x-3.5-x-1-incher packed Windows XP onto a 20GB disk, using Bluetooth, Wi-Fi, FireWire and USB to connect to the outside world. Later models ran Windows Vista.

The Model 01 made it into Guinness World Records as the smallest full-featured computer, and it defined a market (some say evolutionary dead-end) for "tweener" devices called mobile Internet devices (MIDs), Internet tablets or ultramobile PCs (UMPCs). The Samsung Q1, Nokia 770 and a flood of Archos products entered this market, but something else was soon to steal their thunder.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott


My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
