ThinkPad: In late 1992, IBM took the compact design of the PowerBook's pointing device a step further in its new ThinkPad series--most notably the $4350 ThinkPad 700C, which ran Windows 3.1, had a 120MB hard drive, a 25MHz 486SLC CPU, and a large and lovely 10.4-inch color TFT active-matrix panel.
As operating systems advanced and their interface's became more graphical, the need for a mouse increased. Prior to the PowerBook 100, users had to go through the hassle of attaching a mouse to their laptop's keyboard. IBM's solution: a little red stick embedded in the keyboard and dubbed the TrackPoint.
