In Pictures: The Apple family tree

Apple platforms through the years

iOS (2007 to present)

CPU class: ARM OS: iOS Development status: Moderated Platform size: 16

iOS began is life as iPhone OS, which itself stemmed from Apple’s OS X desktop OS. This touchscreen operating system powers three distinct hardware subplatforms: iPhone, iPod touch, and iPad. Each contains a CPU based on the ARM microprocessor architecture. Many iOS apps can run on all three subplatforms, while others are limited to or optimized for a certain iOS device class.

iOS initially shipped on the 2007 iPhone without the App Store or any means of installing third-party applications. In 2008, Apple launched the App Store, and iOS quickly became one of the most populous software platforms of all time.

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.

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.
