Abstract
Abstract A flexibly interfaceable portable computing device includes a display coupled to a processor, which is coupled or selectively coupled to either or both of a keyboard and a recording unit. The display and the keyboard provide a first user interface to the processor. The recording unit is superimposable with a removable markable surface. A stylus allows user marking on the markable surface. The stylus provides a stroke signal and a stroke mark. The recording unit, the markable surface, and the stylus provide a second user interface to the processor. Optionally, the display also contributes to providing the second user interface to the processor. Switching among viewing modes for the display, and synchronization of information between the processor and a processor of the recording unit are also provided. A casing can enfold the display, the keyboard, and the recording unit to form a relatively slim profile. A portable computer system can have a display, a keyboard, and thick components enfolded and/or located within an overall thickness substantially equal to a sum of a first thickness for the display plus a second thickness for the keyboard, to present a slim profile.
