Toshiba Portégé M400-S933


The Toshiba Portégé M400-S933 is a tablet PC loaded with laptop features, such as a keyboard, fingerprint reader, and built-in optical drive.

Built-in optical drive. Fingerprint reader. Good security. Expandable hard drive. Good heat management.

Noisy mouse buttons. Too much lag when switching between portrait and landscape modes

Toshiba Portege M400-S4032


The Toshiba Portégé M400-S4032 ($2,200 street) is a terrific convertible tablet PC with a rotating display that makes writing on the screen fun. The second iteration of the Toshiba's M400 series, the M400-S4032 includes a significantly improved set of...

Integrated Verizon EV-DO. Intel Core Duo processor. Built-in optical drive

Cramped keyboard. Low battery life

If prestige is what you're after, the M400-S4032 is the only convertible tablet currently available that's blessed with both integrated EV-DO wireless and a dual-core processor.

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

Review Toshiba Portege M400


The current review of the Toshiba M400 Tablet PC represents a spe

attractive design ; a construction, solid and rigid against torsions ; intelligent display mechanics and catch hook system ; good values of brightness and illumination measurements ; low temperature emissions ; acceptable battery runtime

partially too low resistance against pressure upon the case ; wobbly battery ; too small keys ; permanently running fan, even without load

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


The Toshiba Portege M400, first released in late Spring 2006 is the successor to the Toshiba Portege M205, one of our favorite Windows XP Tablet Edition convertible notebooks. We loved the M205's better resolution (most tablets were XGA and the M205...

Good performance and very good battery life. Plenty of ports, good viewing angle, internal optical drive means you can watch DVDs on the plane. Intel wired and wireless networking are strong and the Bluetooth option offers 2.0 + EDR speeds. Biometric...

Standard XGA resolution doesn't put the M400 ahead of the tablet competition. No recovery media included so you must burn your own CDs (about 10 of them!)

The Toshiba M400 is a bargain among Windows XP Tablet Edition convertibles. The Core Duo (now standard), SATA hard drive, optical drive and plenty of ports make this a very capable portable, yet the notebook is light and very compact. We love having...

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.
