Articles reviewing hardware performance benefit tremendously when you actually provide something to compare it to. You can't assume that everyone knows instantly how good or bad a benchmark score is. It might be possible for someone to go find another review for comparisons, but that may entail having to go to other sites, and track down multiple reviews just to determine a baseline. It certainly isn't conducive to keeping readers at your own site.

cute little notebook. i'd like something like this for office/travelling work because i believe in having a desktop as a main rig for gaming/heavier work.(upgradability/raw computing power). still, this office minibook/home rig situation is some time away as i am still at college :)

IMO This Is A Great Product:

I've been using the U100 since June 2005 as a go-anywhere, do-almost-anything, clone of my main computer (Tecra S1) and I'm delighted with it. The fingerprint reader is surprisingly useful and I can now type nearly as fast on the U100 as on the main laptop.

At first I some screen text too small to read but I found a nice solution, described below with some other tweaks:

Display Tweak:
Right-click on desktop, choose Properties, and click the Settings tab. Click the Advanced button and select the Monitor tab. Ignore the warning beneath the box 'Hide modes this monitor cannot display' and uncheck it. Click OK and then change the Screen Resolution slider (in Display Properties) to the previously undisplayed value of 1280 x 1024. This gives a virtual screen larger than the physical screen but when you mouse to top or bottom, the screen pans up or down to suit.

Now click the Advanced button again, open the General tab, and change the DPI setting from 96 to a 'Custom' value of 144 (150% normal size) and click OK. This makes most text 50% larger. (If you do this without altering the Screen Resolution you'll find that with some windows the OK, Cancel, and Apply buttons become inaccessible off the bottom of the screen). Most screens work ok like this although the text may become a bit cramped in some (e.g., Toshiba Power Saver).

Mouse Tweak:
To make the mouse pointer more usable, open Start/Settings/Control Panel/Mouse, select Pointer Options tab, and set pointer speed to maximum and tick the box 'Enhance pointer precision'.

Zooming:
Toshiba's Zoom function is ok for desktop icons but not so good for in Internet Explorer because you have to readjust the zoom every time you change page. I found the best solution is to use Opera as default browser instead of IE. It has an excellent zoom function built-in and you can zoom using the mouse wheel or just by pressing keys 9 or 0.

No Caps Lock Lamp
The small keyboard meant that, at first, I was always pressing Caps Lock when I meant to press letter 'a'. Now I'm used to it, I can type on it nearly as fast as on my main laptop (Tecra S1) so it's not such a big issue. However a Caps Lock warning is still useful.

I found a nice solution at

Here's a direct quote from the link: "You can modify Windows to make a sound each time the Caps Lock button is hit. Do this by clicking on Start, Settings, Control Panel, Accessibility Options and on the Keyboard tab click the Toggle Keys check box. Now when you press Caps Lock it will make a sound, and when you press it again to turn it off it will make a different sound. With this enabled the accidental press immediately becomes noticeable."

It works fine. Assuming the volume control is not set to zero, I get a high-pitched bleep when Caps Lock is enabled and a low bleep when it turns off.

I would like a machine to use both on the road and in the office - has anyone used the machine with an external keyboard, mouse and monitor when at the office?

Tosh's Libretto U100 (AKA The Little Black Machine) is Dynamite, Fantastic, Awsome. Hello Tosh! Got a Toshiba? Things can only get better now that I've found you and I don't mean NEW LABOUR!! As you can see I'm Loving It ....DA.. DA.... DA ......DA ..DA

What do you think about Fujitsu Lifebook P1510 vs Libretto U100?
P1510 has similar weight to Libretto (1.0 Kg) and bigger screen (8.9") and is TabletPC convertible.

i like your method of review. it takes into consideration common reactions one can have while studying the gadget.anyway, the review tells me, of course provisionally, my decision to buy a libretto u100 will stand the test of time.in next few hrs, it will be physically in front of my eyes.

The Libretto U 100 is a fantastic machine but it doe's have one real bad point.
In my opinion the screen is very fragile, and is not protected enough by the 2 piece outer cover.I know because mine broke after just five days of use ,and was protected by a leather laptop case and a hard laptop case.
Its seems that Toshiba has gone for looks at the cost of strength, and when you put that with poor service and no spare screens stocked by the repair partners, you have a recipe for disaster.
Also what is going on with this hard drive being built into the bowels of the unit meaning a complete strip down to remove the hard disk?
This won’t appeal to people that don’t want to pass on there laptop to someone else, when they have finished with it. without swapping the hard disk for a new one.
I say well-done Toshiba in bringing the Libretto back, ten out of ten, but for service support, and business user support I say five out of ten with big room for improvement.
I also say that , when you hear comments from your end users, don’t try to wriggle out of claims, learn by your mistakes and embrace your critics, this way you and your products will move forward from strength to strength

on my trips (SF), it was so great to have. small and i can even use it as DVD player!!

Because Ihave access to alot of regular laptops, having this small size Libretto makes the diference!

very detailed information

I love my U100. I'm amazed a how much this little unit can take on. The finger swiper does double duty as a scroller and third button!

I have also found that people are more comfortable with me pulling it out in meetings etc.

I was drawn to he device because I was sick of my PDA having no serious storage space. Skipped the UMPC (crap screen resolution) next step up was the U100. If I was prepared to spend another $1000 It wold then have been a tablet.

Don't buy it to write a book on.... It's pure toy! And damn fun!
