CNET has published the rarest of beasts, a hardware review that gets it right all the way through. The review of the Toshiba Tecra M4 covers all the basics, specs, configuration, ports and screen, and they also do a very good job describing the shortcomings of the M4 (weight and screen glare) as well as who this Tablet PC is perfect for. Good review and worth checking out if you are interested in the M4. From the review:
With a silver lid and a black base, the Toshiba Tecra M4 convertible tablet looks right at home in the boardroom. It is solidly designed and loaded with features, but its 6.2-pound weight is a killer if you want to hold your tablet like a clipboard for any length of time. If you want a decent laptop with tablet functionality, the Tecra M4 provides top-notch performance, a comfortable keyboard, and a large 14-inch screen. If you’re looking for something to use primarily as a tablet, you’re better off with smaller devices such as the ThinkPad X41 or the Motion LE1600.
