The Powerbook series of Apple laptop computers had a unique design with a build-in trackball. While the original powerbook, the Powerbook 100, was appreciated in the market (1991) but highly underpowered. The fifth model of the powerbook, the Powerbook 180, was highly capable (oct 1992), but a a steep price of US$3870 for the base model with 4 MByte DRAM.
The Powerbook 180 had an Active Matrix LCD screen (much better than the Twisted Numatic LCD screens of the previous models). Also the interface capabilities, external color monitor, external SCSI harddrive, were excellent. The model was highly priased for its design, acquiring the title for the Powerbook 100 of the 10th greated design of computers of all time (PC Worrld, 2006).
