It was a pretty good week last week in the world of mobile devices. Toshiba released a Pentium 4 desktop replacement notebook, Mitsubishi unveiled a pocket projector that shines wide, and Tatung launched its first tablet PC. Here's a brief note about each of the products:

* Toshiba releases Pentium 4 desktop replacement notebook

Toshiba's Digital Products Division launched the Satellite P35-S611, a desktop replacement notebook that starts at $1,799. Features include TruBrite technology to create extreme brightness and images that can be viewed across the room; a 17-inch wide-screen display and an anti-glare coating that Toshiba says enhances viewing angles.

The notebook features a 3.33-GHz Intel Pentium 4 processor 548 with 533 MHz front side bus and 1M-byte of L2 cache. It also comes with an ATI Mobility Radeon 9000 graphics card with 64M-bytes of shared memory, 512M-bytes of DDR SDRAM (expandable to 2G-bytes), a 100G-byte hard drive and a DVD-SuperMulti drive (supports both DVD +/- formats). It supports the 802.11b/g wireless LAN (Atheros chipset), has three USB 2.0 ports, an IEEE 1394 port, a bridge media adapter (supports Secure Digital, Memory Stick, Memory Stick Pro, SmartMedia, MultiMedia Card, and xD-Picture memory cards); and a 12-cell lithium-ion battery.

The system weighs about 9.49 pounds (remember, this is a desktop replacement system, not something you're going to carry around too much), and runs Windows XP Home. More details on the system are available at Toshiba's Web site (http://www.toshibadirect.com).

* Mitsubishi's small projector shines big

The Presentation Products Division of Mitsubishi Digital Electronics America last week launched the PocketProjector, a very small LED projector that can create a 20-inch diagonal screen with just over one foot of projection distance or a 40-inch screen with less than three feet of distance. The device weighs only 14-ounces, can fit into the palm of your hand or a coat pocket, and works on batteries or with a universal car adapter. The projector will cost about $700 and will be available in July, Mitsubishi says.

The projector can connect to and display images from a notebook, portable DVD player and gaming consoles, and produces an SVGA (800 by 600 pixels) image, Mitsubishi says. The projector has an average lamp life of about 20,000 hours, the company added. Optional "convenience packs" will sell for $199, which include application-specific cables, and accessories for small screens. An extra battery base will be available for $149, Mitsubishi says.

* Tatung's first tablet

Tatung Science and Technology launched its first tablet, the TTAB-B12D 12.1-inch tablet PC. The device can be configured with either an Intel Pentium Mobile LV 1.4 GHz processor, Mobile ULV (1.0, 1.1 or 1.2 GHz) processor or Intel Celeron M ULV (900 MHz) processor, Tatung says. The device weighs 3.08 pounds, measures 0.73-inches thick, and has a stylus for handwriting or can be attached to an optional keyboard or docking station. With the docking station, the tablet can be rotated 90 degrees to let viewers see the display in either a portrait or landscape mode.

The tablet also includes the Omni Pass AP biometric fingerprint recognition for additional security, letting user log-in with a swipe of their finger. Other features include a 30G- or 60G-byte hard drive, integrated 10/100 Ethernet, 802.11a/b/g or 802.11b/g WLAN, V.92 modem card, two USB 2.0 ports, a IEEE 1394 port, and infra-red connectivity.

Prestigio releases a mobile multimedia center

For customers in Eastern Europe, the Middle East and Asia, South Korea-based Prestigio has launched a high-performance notebook-based multimedia center named Nobile 159W. The system includes InterVideo's InstantON feature that lets users play CDs, DVDs, MP3s and view photos without having to load the computer's operating system.

The 159W includes a 15.4-inch WSXGA+ (1,680 by 1,050 pixel resolution) LCD screen, 256M-bytes of dedicated video RAM (ATI M11 graphics card), regular memory expandable up to 1G-bytes, and the Intel Pentium M processor (up to 2.0 GHz). Another unique feature is a sloped, ergonomic keyboard to help promote comfortable typing.
