Toshiba Portege M400-S4032


Toshiba's excellent convertible gets even better with Core Duo and built-in EV-DO.

Durable design • Good productivity performance • Low price

Short battery life • Limited tech-support hours • Noisy fan

UEBO M400 Wi-Fi Media Player Reviewed


Uebo's M400 plays a wide array of media formats. But its lack of polish and noisy fan may outweigh its relatively inexpensive price.

Low cost ; User-installable drive ; Large feature set ; Wide video format support

Buggy in spots ; No native Netflix support ; Noisy fan ; Spotty metadata handling

HD networked media player with extensive format support and user-installable hard drive

Toshiba Portege M400 Tablet


A few weeks ago we looked at Toshiba's Tecra M6, not a particularly sexy notebook, but one designed for productivity and dependability. While the design could have used some refining and the notebook was not really exceptional in any way, the M6 proved...

Is Toshiba's Portege M400 Tablet PC Too Large For Comfort


Tablet PC is a great idea both as a hardware concept and an operating system. However it doesn't work well in any and all circumstances. Toshiba may have hit at least the conceptual limits of Tablet PC with its Portege M400.

Toshiba's Portege M400 sports a decent set of hardware components. It's also ergonomically a pretty good mobile computer in standard clamshell open mode. It has a typically small keyboard and touchpad, both of which I'd like to see drastically...

Toshiba Portege M400


When the Tablet PC platform was launched back in the Fall of 2002, Toshiba was the only one to offer a notebook convertible with a 12.1-inch display. Acer had gotten all the big attention with its little C100, the device that pioneered the notebook...

Like almost all Tablet PCs, the M400 uses the Wacom digitizer with its sleek active pen that does not need batteries. The pen garage is on the right side of the computer where you're never quite sure if the pen is there or not. I much preferred the...

Tim Hillebrand on Mobile: Toshiba Portege Duo Core M400 Tablet PC


My very first laptop was a Toshiba, and was I ever proud of it. It had not one, but TWO 3.5 inch floppy drives and a sizzling 900 baud modem. I was the envy of everyone, and I was smugly convinced that I possessed the pinnacle of laptop computing. If...

Like the reviewer, I've owned Toshiba laptops on and off for the better part of twenty years, including six Porteges. Porteges have always been premium products with excellent build quality and a terrific mix of features and ergnomic excellence in a...

Toshiba Portege M400 Tablet PC review


With Microsoft launching Vista earlier this year with an aspect of the Tablet PC format integrated into it, it seems the software is here for the foreseeable future. With this in mind, manufacturers have been overhauling their designs, with the latest...

Dual-core, built-in 3G

Toshiba Protégé M400 laptop review


The Toshiba Protégé M400 is the company first Intel Core Duo processor based Tablet PC, so has the extra boost in performance made the Tablet PC attractive? We take a closer look. Light and compact, the M400 features a swiveling 12.1-inch display at...

Compact, light, easy to use, vertical mode great for viewing websites

Not sure why you would want a Tablet PC, Not the fastest offering on the block

The Toshiba Protégé M400 works well and does what it sets out to do, however we are still struggling to see why you would want a WebTablet in the first place
