Toshiba Libretto U100 ultraportable notebook

Good things, small packages?

Review Toshiba has been designing and manufacturing notebooks for 20 years, starting with the T110 in 1985, which weighed in at over 7kg, had a battery life of 60m and possessed a green screen. To celebrate, the company has chosen to revive one of its older ultraportable lines, in the form of the Toshiba Libretto U100. Initially there will be this one model but if it proves popular, the line will be expanded, writes Stephen Patrick.

Toshiba Libretto U100The U100 is no normal laptop. Instead, it's a showcase for how far miniaturisation has come. The U100 looks and feels more like a shrunken notebook. Its proportions are in keeping with larger machines - it's not a slimmed down ultraportable.

The U100 isn't really intended to be used as your only computer. Rather, it should be used as a portable on the move - its size makes it ideal for carrying in your overnight luggage or even your day bag. With a weight of 1kg and dimensions of 21 x 14.5 x 3.5cm, it won't be a burden.

The 7.2in screen is backlit using LEDs, a technology not usually found in notebooks. The benefit is its power efficiency - it's far less power hungry than alternative technologies. On the downside, image quality isn't as bright and images have a slight haze to them. Image quality is enhanced, though, by the use of a Toshiba TruBrite anti-glare layer.

The Libretto is fitted with an Intel 1.2GHz Pentium M 753 ULV processor. Designed with battery life rather than raw processing power in mind, you'll find you'll be able to use the U100 for writing reports and using as an email client but you won't want to run anything too demanding on it. Battery life more than compensates, though, with four hours possible without worrying too much - impressive given the size of the battery cell on the machine.

Toshiba ships the U100 with a docking station, which doesn't add to the array of ports but merely houses the optical drive - in this instance a dual-format DVD rewriter. For such a small chassis, there is a wide array of connectivity on-board the U100. With two USB 2.0 ports alongside two Firewire - one mini and one full-sized - as well as PC Card and SD card slots, you'll find as much scope to add cables as a standard laptop offers.

Miniaturisation has its drawbacks and can often lead to cramped and awkward handling. While the keyboard is on the small size, it's comfortable to use. The mouse button and pointing-stick are a different matter. With such a small keyboard, the pointing stick has been moved to sit between the mouse buttons, which makes using them both a two-fingered operation and fiddly at best.


The Toshiba Libretto U100 is an amazing notebook that highlights many of the technologies that make Toshiba one of the leading laptop manufacturers in the world. While you won't want to use the U100 as your main machine, for use on the move it's a powerful and flexible portable with an impressive battery life for its size.

    In-brief Governments around the world should pass intellectual property laws that grant rights to AI systems, two academics at the University of New South Wales in Australia argued.

    Alexandra George, and Toby Walsh, professors of law and AI, respectively, believe failing to recognize machines as inventors could have long-lasting impacts on economies and societies. 

    "If courts and governments decide that AI-made inventions cannot be patented, the implications could be huge," they wrote in a comment article published in Nature. "Funders and businesses would be less incentivized to pursue useful research using AI inventors when a return on their investment could be limited. Society could miss out on the development of worthwhile and life-saving inventions."

    More papers describing the orders and messages the US President can issue in the event of apocalyptic crises, such as a devastating nuclear attack, have been declassified and released for all to see.

    These government files are part of a larger collection of records that discuss the nature, reach, and use of secret Presidential Emergency Action Documents: these are executive orders, announcements, and statements to Congress that are all ready to sign and send out as soon as a doomsday scenario occurs. PEADs are supposed to give America's commander-in-chief immediate extraordinary powers to overcome extraordinary events.

    PEADs have never been declassified or revealed before. They remain hush-hush, and their exact details are not publicly known.

  • Stolen university credentials up for sale by Russian crooks, FBI warns
    Forget dark-web souks, thousands of these are already being traded on public bazaars

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.
