DVD Writers

Who supports which standard

In case you are in any doubt, each DVD standard maintains its own list of supporters from some of the most influential industry players.

DVD-RAM is backed by Hitachi, Toshiba, Panasonic and Samsung, and is also endorsed by the DVD Forum. DVD-RAM was the first standard developed by the DVD forum, and the first format used both in PC drives and in DVD recorders for the living room.

DVD-RW is also endorsed by the Forum, and is backed by Pioneer, NEC, Sharp and Thomson. This format also features in systems by Apple and Compaq. The Forum also supports the write-once DVD-R format, which is recognised as the DVD equivalent of CD-R media. This is the most versatile standard, as all DVD writers except the DVD+RW will operate with this format.

DVD+RW is not endorsed by the DVD Forum, but does have the support of the DVD+RW Alliance. This Alliance consists of Hewlett-Packard, Philips, Sony, Yamaha, Verbatim, Ricoh and Dell. Microsoft also announced its intention to join the DVD+RW alliance in February 2003. Like the DVD Forum, the DVD+RW Alliance has developed its own write-once format, DVD+R, which claims to offer a level of drive compatibility similar to that of DVD-R.

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.

Steph Mundell


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.
