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, email, 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 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 a reasonable price.

Good: An amazing laptop. Fast, long battery life, performance of a laptop and convenience of a tablet
Bad: Perhaps the fan noise?
Comment: I bought this laptop when it first came out, five years ago. From the day I got it I knew it was the best computer to me in every way. I am twelve now, and have had this since I was seven. My Dad also had one for ages, and then gave that one to my brother after four years of continuous use. I have to admit, I did modify it a bit, I put 2 gigabytes of RAM in there, but still, even with the preinstalled ram, it never lagged, and could run at least 20 programs at once, but that was a bit heavy on the cpu. Recently, after accidentally held town the task manager or windows security button, as Toshiba call it, I managed 437 windows open at once, all responding and all with moving elements. The fact that it is light weight, means that I can carry it around and us it for school. It will fit easilly in my school bag, and with it high resolution screen, I was able to plug a microscope into the USB port and after putting it in tablet mode, I was able to hang it up with a few photo pins on the science lab wall. This convinced my teacher to get one. I can't really think of many major drawbacks, but people say my fan is too loud, but I fixed that with a BIOS upgrade.
