Nevertheless, even with its new Core Solo processor, the Portege M400 didn't pull off superspeedy scores in CNET Labs' mobile benchmarks. Though the tablet beat the slow ThinkPad X41 Tablet, it fell behind most of the other Pentium M tablets we've tested. You're not likely to notice the difference when performing basic mobile tasks such as note-taking, e-mail, and word processing; though if you're interested in running more high-powered apps, we recommend the LifeBook T4020 or (if you can handle the extra weight) the $2,049 Toshiba Tecra M4. In our Labs' battery drain trials, the Portege M400 lasted for 4 hours, 20 minutes--not bad, but not great compared to the HP Compaq tc4200, which cut out just 4 minutes shy of 5 hours, and the ThinkPad X41, which lasted for 5 hours, 25 minutes, thanks to its considerably larger battery. Though the Portege M400 doesn't offer an option for a high-capacity primary battery, you can purchase a secondary battery for $199.
Toshiba backs the Portege M400 with a one-year warranty with return-to-depot service, though customers can extend their time up to four years through one of the company's reasonably priced warranty upgrade options. Around-the-clock, toll-free phone support is available for the life of your warranty. The Toshiba support Web site offers the requisite downloads and FAQ information, along with a helpful user forum operated by the Windows Users Group Network.
