Free Opera browser takes on Explorer, Netscape

The Opera for Windows 5.0 browser contains news and e-mail clients, integrated Web search and instant messaging functions, and supports plug-ins. It is a 1.89MB download, with code to enable Java and Java plug-ins adding 7MB to the file size. In comparison, a full install of Internet Explorer version 5.5 requires 111MB of hard disk space, and a minimum install requires 45MB. A complete install of Netscape Communicator version 4.7 requires 14MB on the hard disk.

"With a smaller browser, you leave more room in your RAM (random-access memory) for data," said Jon von Tetzchner, Opera's chief executive officer. "And with the file size as small, it opens the door for Opera to run on smaller devices."

Opera has versions for the EPOC operating system used in mobile telephones and other portable devices, as well as a Linux version in beta-test stage, a Macintosh OS version and a version for BeOS. Tetzchner said he would consider working toward a PalmOS version when RAM and screen size improves on personal digital assistants.

Microsoft's Internet Explorer and America Online's Netscape products lead browser sales worldwide, in large part because personal computers are often sold with the software bundled in, or can be downloaded for free. The free version of Opera carries banner advertising, while the browser without ads costs $US39. "People say they would use Opera, if they wouldn't have to spend money to buy it," said Tetzchner. "This gives them an option."

He said Opera has between one and two million users of its browser software worldwide.

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.
