When they're not trading tales of taxi-line traumas and bad-hotel horror stories, frequent travelers like to swap brags and boasts: One time I jumped from standby for coach to a free seat in business class. I made it from O'Hare gate C2 to B17 in ten minutes flat. Or, with the Logitech Bluetooth Mouse M555b: I edited the entire annual report with only a two-inch strip of mouse room on my tray table. I scrolled through 4,000 spreadsheet rows in eight seconds.
The M555b ($50) is Logitech's newest mobile mouse, designed for notebooks and netbooks with built-in Bluetooth wireless. Hence it has no USB receiver to fuss with, unlike most cordless mice. Its laser sensor works smoothly on a good variety of surfaces (with the universal optical-mouse exceptions of glass and mirrors), while its 1,000 dpi resolution lets it work in only a couple of inches of maneuvering room.
Like other notebook mice, it's a tad smaller than the desktop variety -- 2.3 by 3.9 by 1.3 inches -- but feels solid enough, at 4.1 ounces with its two AA batteries, to track without skating or wobbling in the hand. Its rounded-rectangle shape should prove comfortable for both left- and right-handed mousers, while the batteries are rated for 10 or 11 weeks between swaps.
Instead of side-mounted or thumb buttons, the Logitech has one extra button on top, just behind the scroll wheel.
