Margus reviewed the T4010 Lifebook notebook from Fujitsu for notebookreview.com. Here's a short blurb from his test report:

The Fujitsu LifeBook T4010 is a Tablet PC notebook convertible device. Fujitsu has more than 60 % of the worldwide Tablet PC market-share and they have been in this market since the beginning, so it seems that Fujitsu has the best experience with this type of product. The T4010 is not a pure Tablet like the Fujitsu Stylistic ST50xx series, the ST50xx is a slate style Tablet PC (no keyboard, just electric pen as input). The T4010 meanwhile is a kind of a "variable" notebook, meaning that in normal mode you can use the T4010 as an ordinary notebook, but when you flip the screen over on top of the keyboard, it transforms into a tablet style device, and thereby brings to the table the advantages of a tablet and notebook all-in-one..
