The state-of-the-art specifications listed below tell you a great deal about this mobile computer; consider the Libretto 100CT has more computational power than all of NASA’s control room used during the Apollo 11 space mission. Although you won’t find a typical Intel Atom processor inside this ultra-portable laptop, the Intel Pentium processor inside the Libretto 100CT utilizes the MMX instruction set used in programs to enhance the performance and capabilities of mobile processors.

Note our review model includes 32MB of RAM and this can be expanded to 64MB (though it’s hard to imagine anyone ever needing that much). The 100CT can be connected to a network through a PC Card network device (Toshiba offers 56k modem or Ethernet adapter at the time of purchase). The 100CT lacks built-in wireless networking due to security concerns; the lack of a broadcasting device make the 100CT much more secure from any potential hacking or monitoring by outside parties.

Despite all its power and technology, the Libretto 100CT is fanless. The only noise coming from the 100CT is from the spinning hard disk. The chassis can get warm under continued usage.

Battery Life

The Libretto 100CT manages between one and a half and two hours of battery life unplugged. This may seem like a short time by some ‘standards’, but Toshiba engineers likely felt that people would be pressured to get more work done if they had less time to do it. The included li-ion battery should last about 500 charge/recharge cycles before requiring replacement; put in perspective, if you discharge the battery twice a week, it’d take five years before you wore it out … no one keeps a computer that long.

A printed manual is included with the Libretto 100CT; it even includes instructions on how to connect to the Internet, use DOS and use floppy disks.
