In Pictures: The Apple family tree

Apple platforms through the years

Macintosh (1984 to present)

Development status: Open Platform size: 210+

The Macintosh platform first emerged in 1984, and it has been with us in some form or another ever since. Over these past 22 years, the platform has seen three major hardware shifts (those between 68K, PowerPC, and x86 CPUs) and one major operating system shift (between Classic OS and OS X).

While some could argue that these three CPU types constitute three separate platforms (and technically, they do), Apple accompanied each hardware shift with emulation layers that preserved backwards compatibility, thus maintaining the spirit of Macintosh between hardware revisions.

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.
