The M45-S351 lasted 3 hours, 7 minutes on one battery charge, dead average for laptops we've tested in the last year. Speed with the 1.73-GHz Pentium M 740-equipped portable was less impressive, resulting in a WorldBench 5 score of 69. A 1.7-GHz/600-MHz Pentium M-equipped Sony VAIO VGN-A190 we tested scored 81, about 17 percent faster. Toshiba's own Tecra M3, also tested for our July 2005 issue, earned a score of 77--over 11 percent faster. While minor, those differences could cost you a few seconds if you're doing heavy data crunching.
