Toshiba Libretto U105 7.2" Laptop (Intel Pentium M Processor, 512 MB RAM, 60 GB Hard Drive, DVD SuperMulti Drive)

Naturally, a notebook this small will have some limitations, and the Libretto is no exception. However, those limitations are not nearly as severe as you might think. This particular model, the Libretto U105, is a "real" notebook in almost every sense, featuring desirable amenities such as a large 60 GB hard drive, a panoramic widescreen display, wireless communications, and adequate 3D graphics support. As you might expect, the system isn't as powerful as a typical notebook, though it's not far off either. The only appreciable difference between this and a standard notebook is in the configuration of its optical drive; it resides in a separate, detachable module that will add an extra lb to the total weight. But if portability and space efficiency are paramount, the Libretto U105 is a top-notch solution.

Processor:
At the heart of any computer lies the CPU (or processor), a massive collection of miniature transistors that governs the speed and power of the entire unit. Some of today's notebooks are equipped with high-end CPU's on par with those found in top-of-the-line desktop PCs, though these machines are usually noticeably larger and more power hungry than their less powerful counterparts. The 1.2 GHz Intel Pentium M 753 CPU incorporated in the Libretto U105 features ultra low voltage technology to improve battery life, lessen noise and keep heat to a minimum. It offers enough speed for standard notebook tasks such as word processing, contact management, finances, Internet and email communications, and CD burning. What's more, it's one of the recently revamped Pentium M models with two full MB of Level 2 cache for even faster retrieval of your most accessed information.

Memory:
Computers typically store information on their hard drive, but they also keep frequently and recently accessed data in Random Access Memory (RAM). More RAM means faster computing, superior multitasking and less strain on your hard drive. The Libretto U105 incorporates 512 MB of RAM, a surprisingly large allotment of memory for such a small computer and more than enough for efficient multitasking and generally smooth response. Moreover, the unit accepts memory upgrades to its 1024 MB (1 GB) maximum.

Video:
CPU's are usually so busy doing basic calculations that they need help translating visual output to the viewing screen. This is the duty of the graphics card (or graphics controller). A graphics controller with "dedicated" built-in video memory is preferable to one with "shared" video memory wherein the graphics controller borrows a portion of the all-important main system memory. This system's graphics controller is an Intel Extreme Graphics 2 with 64 MB of shared, not dedicated, video memory. The Radeon name is highly regarded in video technology, and indeed this system and this chipset will efficiently deal with 2D graphics and do a reasonable job with simple 3D visuals such as those found in older games and entry-level 3D animation. However, it is not well-suited to the latest high-end 3D animation and graphics programs and the current breed of sophisticated computer games.

Display:
As you might expect, the impressively diminutive Libretto U105 is not equipped with a sizable display. Its 7.2-inch screen is simply not ideal for highly detailed, graphically intensive work, though it does sport a panoramic, widescreen format that's well suited to DVD movies. Its highest supported resolution of 1024 by 768 is adequate for most applications and typical of this price range, and its Toshiba TruBrite technology helps keep images bright and clear.

Hard Disk:
The Libretto U105 features a 60 GB hard disk. This may not seem large when compared with the 80 and 100 GB monsters now found in today's substantially bulkier "desktop replacement" notebooks, but it's very spacious for a highly portable ultra-light. Users should have little problem storing a full allotment of applications and data files and even a library of multimedia and music files.

Optical Drive:
An optical drive is essential in today's computing environment. A "CD-ROM" drive allows you to install CD-based applications and play music CDs. A "CD-RW" drive adds CD "burning," so you can also backup your important files to long-lasting discs and create personalized music CDs. With a DVD-ROM drive you can watch DVD movies. And with a DVD-RW drive, you can "write" home movies to durable discs and archive files to DVD (DVDs boast more than seven times the storage capacity of a CD). Some drives allow you to do a combination of all of these tasks. This system features a "DVD Multi Drive" that supports all of the above. It is important to note that this drive is housed in a separate detachable module that increases the system's size and weight.

Audio:
The Libretto U105 features an integrated 16-bit audio processor and built-in stereo speakers that, through the enclosed software, mimics the spatial awareness of surround sound.

Keyboard and Controls:
You'll control your notebook via an 84-key keyboard with HotKey function and a Toshiba Accupoint pointing device.

Connectivity and Expansion:
The Libretto U105 offers a wide variety of ways to keep in touch, including a 56K modem for low-speed dial-up Internet and email access, an Intel PRO/100 VE network connection for high-speed wired network and Internet, and integrated wireless 802.11b/g LAN for cordless e-communication in today's two most popular formats, Wireless-B and the considerably faster Wireless-G. Other key amenities include three high-speed USB 2.0 ports for fast interaction with plug and play devices such as external drives and digital cameras and an IEEE 1394 FireWire port (commonly used for quick data uploads from digital camcorders). A memory card reader is not included.

Operating System and Software:
Toshiba has fitted the system with Microsoft's sophisticated business-oriented operating system, Windows XP Professional Home Edition. Other applications include Microsoft's Works productivity suite and Microsoft's One Note note-taking utility.

Dimensions and Weight:
Notebook computers are manufactured in a wide variety of sizes and weights. Many of today's most powerful notebooks are also the largest, weighing ten or twelve lbs or more and therefore too big and cumbersome for extensive, continuous traveling. These are often referred to as "desktop replacements." On the other extreme are "thin and lights" or "ultra-portables," super-miniaturized units that typically aren't as powerful as their larger brethren but weigh as little as two lbs and will often fit comfortably inside a large purse. At just 8.27 by 6.5 by 1.17 inches (w/o optical drive), and a scant 2.16 lbs (w/o optical drive) and 3.2 lbs (optical drive attached), the Libretto U105 is a stunning example of miniaturization.

Power:
The system is equipped with an 6-cell rechargeable Lithium-ion (Li-ion) battery that delivers an amazing five hours between charges.
