Sharp Actius RD review: Sharp Actius RD

Review Sections

Performance analysis written by CNET Labs assistant lab manager Eric Franklin.

System configurations:

Sharp Actius RD3D
Windows XP Pro; 2,800MHz Intel Pentium 4; 512MB DDR SDRAM 266MHz; Nvidia GeForce4 440 Go; Fujitsu MHT2060AT SP 60GB 4,200rpm

Sony VAIO PCG-FRV37
Windows XP Home; 2,800MHz Intel Pentium 4; 512MB DDR SDRAM 266MHz; ATI Radeon IGP 345M 64MB; IBM Travelstar 60GN 60GB 4,200rpm

Toshiba Satellite A25-S279
Windows XP Home; 2,800MHz Intel Pentium 4; 512MB DDR SDRAM 266MHz; Trident Video Accelerator Cyber-XP4 32MB; Toshiba MK4004GAH 40GB 4,200rpm

Although the Sharp Actius RD3D lowers its CPU speed while unplugged, this unfortunately does not translate into exceptional battery life. The system, with its 11.1V, 6,000mAh (67WHr) battery, came in second place in CNET Labs' tests with more than two hours of battery life, while the Sony VAIO PCGFRV37--with its less powerful 14.8V, 4,000mAh (59WHr) battery--came in just two minutes behind. Thanks to its 10.8V, 8,400mAh (91WHr) battery, the Toshiba Satellite A25-S279 was able to break the three-hour barrier, by nearly 40 minutes, to come out on top. As the Sharp Actius RD3D is a desktop replacement, not much weight should be put on its battery life.

To measure mobile application performance and battery life, CNET Labs uses BAPCo's MobileMark 2002. MobileMark measures both application performance and battery life concurrently using a number of popular applications (Microsoft Word 2002, Microsoft Excel 2002, Microsoft PowerPoint 2002, Microsoft Outlook 2002, Netscape Communicator 6.0, WinZip Computing WinZip 8.0, McAfee VirusScan 5.13, Adobe Photoshop 6.0.1, and Macromedia Flash 5.0).

Sharp backs the Actius RD3D with a one-year warranty on parts and labor, which is typical for the industry, but a longer standard warranty on a system this complex would be better. Boosting your coverage to three years would be a well-spent $200. In addition to good general troubleshooting tips, you'll find downloadable manuals, drivers, and setup help on the Sharp Web site. Our favorites are the searchable knowledge base and several tutorials on getting the most out of this unique 3D screen, including how to clean and care for it. At any time, day or night, you can call Sharp's toll-free support line or send e-mail with a problem.
