1991 — HP 95LX pocket computer
In 1991, HP introduced a pocket computer aimed squarely at the enterprise worker. The HP 95LX was similar to the Poqet PC in that it also ran MS-DOS, but HP included software in ROM that turned the 95LX into a business tool.
Most significantly, HP included the main spreadsheet program Lotus 1-2-3 (thus the Lotus Expandable LX designation) in ROM, producing a full spreadsheet computer that fit in a pocket. There was also a financial calculator, PIM software, and other goodies embedded in ROM, making the HP 95LX a true busines powerhouse.
Like the Poqet, the HP 95LX was a full DOS PC and could be programmed by the user. HP continued to produce upgraded models for a few years before retiring the product line.
