Optical mouse proves that two `eyes' are better than one

After falling in love with optical mice earlier this year, I found myself noticing a serious problem. Sometimes my cursor would get stuck in the corner of my monitor screen - virtually disappering - then failing to move quickly enough as I frantically whipped the little rodent all over the desk.

Logitech has found a solution to my troubles. The MouseMan Dual Optical ($50) has not one, but two "eyes" on the underside for better cursor maneuvering on your computer monitor.

The two 800 dot-per-inch optical sensors, set at a 45 degree angle from each other, send separate signals to a synthesizer that combines information for more accurate feedback and better tracking.

Some gamers have had trouble with optical mice when making quick movements in first-person shoot 'em ups like Star Trek Voyager: Elite Force. For a gamer who moved his mouse too quickly - say to whip around a phaser rifle to blast an alien - the mouse wouldn't track properly. I plugged in a mouse with a regular rollerball to play such games.

The MouseMan Dual Optical handled such high speed maneuvers efficiently most of the time. Over about six hours of play, I had two mousing errors - far better than other optical mice, which were unacceptable for gaming.

If you're using your mouse to get from one word processing document to the next or some other mundane task that most of us perform on our computers, the MouseMan performs well without lost cursor syndrome or jerky movements.

It also is well contoured to the hand, making it comfortable to push around your desktop or even on top of your leg.

The MouseMan is compatible with Windows 3.1 or higher and Macintosh 8.6 or later operating systems. And it will be compatible with Windows XP.

Big Sony monitor offers impressive view

When it comes to computer displays, size does matter. The GDM-FW900 Trinitron Color Graphic Display by Sony is an impressive 24-inch Cathode Ray Tube monitor with a 4-plug Universal Serial Port hub offering awe-inspiring graphics capabilities.

Sony's big monitor is geared toward graphics professionals and others who want to edit photographs, perform desktop publishing or enjoy gaming at the best possible image size.

The GDM-FW900 has a 22.5-inch viewable image size that can support a 2,304 by 1,440 pixel resolution. That means that if you want to see two pages side by side, you can.

With all of that screen real estate, I could open up more menus and toolbars in Photoshop and some of my other desktop publishing programs while getting a full view of the document or image I was working on.

The flat face of a Trinitron reduces distortion across the screen and especially in the corners, while also cutting down on glare. The display itself really came alive in my gaming experiences with the monitor taking full advantage of my high-end graphics card which created crisp, colorful images for a range of games.

Despite the fact that it took up about the same amount of space as most 21-inch CRT monitors, the GDM-FW900 ($2,000) has one heck of a footprint, so if you're short of space, it makes sense to buy a LCD monitor rather than try to fit this 93-pound monster on your desktop.

But if you have the room for this kind of graphic extravagance, you won't be disappointed.
