Introducing the world’s first notebook PC with Microsoft® Active Notifications. Whether the computer is on or in suspend mode, Active Notifications can automatically receive or retrieve email and calendar items so they’re ready and waiting when you need them, visible on the Toshiba Edge Display.

Created to harness the innovation in the Microsoft® Windows Vista™ operating system, the Portégé® R400 is an exquisite notebook and an elegant Tablet PC all in one. Encased in a scratch-resistant ultraviolet clear-coat case, the 12.1″ diagonal backlit LED wide-screen high-brightness display with wide viewing angles, in conjunction with Microsoft® Windows Aero™, delivers a rich visual experience. And with advanced EasyGuard™ security features, including a biometric fingerprint reader, multi-level passwords and TPM encryption module, the Portégé® R400 is as secure as it is attractive

The R400-S4391 takes advantage of Vista in other ways. Along the front bezel, you can find an LCD panel that displays text using a feature in Vista called SideShow. The idea here is to relay e-mail messages, RSS feeds, and text messages over to a secondary display. The display is big enough only for text, but it consumes little power and can be kept on without booting into Vista. The data scrolls across this display, much like a stock ticker. You can flip through the messages using the three buttons next to the display.

Review By Laptophacks

Take a look at the R400. It’s a beautiful machine. My hotel room picture really doesn’t do it justice, but even the picture gives you a sense of what a looker this high contrast black and white notebook is. Now, here’s the kind of funny part. When you twist the screen and fold it down to make a Tablet PC, most of the R400 is a nice, but monochromatic black. All of that beautiful white remaining is the small bit along the edges of the notebook. If only the entire twist-and-fold display of the R400 were transparent like those new fangled Aero windows in Microsoft’s Vista, then the great white keyboard deck could shine through.

With an ultralow-voltage CPU and a lack of power-hungry components, we expected more battery life from the Portege R400 than the paltry 1 hour and 54 minutes we got in CNET Labs’ DVD battery drain test. Windows Vista can be power hungry, and the secondary edge display probably doesn’t help, but at least three hours is what we’d expect from tablet PCs, which are intended to be mobile by their very nature. Our review unit included a second, extended battery pack (which we have not tested yet) which clips onto the bottom of the system. That would add considerable work time but also add weight and bulk to the system.

Finally, the wireless docking solution is a very innovative feature that many will be interested in with the R400. Basically what happens is that when you put the notebook within 3 feet of the wireless docking solution that uses UWB (Ultra Wide Band) to communicate with the R400, the notebook will automatically “dock”. Meaning that anything plugged into the ports of the wireless dock will be accessible to the R400. Streaming video to the dock, from the laptop and to an external screen is entirely possible given the fast wireless connection UWB offers. The wireless docking solution means no more trying to fiddle getting a notebook into the dock and slotting it in properly, then locking it in place.
