The GridPad (stylized as GRiDPad) is a discontinued family of pen-enabled tablet computers and hybrid laptops built by Grid Systems Corporation.
The GRiDPad 1900, released in 1989, is regarded as the first commercially successful tablet computer and predecessor to modern 2-in-1 devices. Jeff Hawkins went on to use the GRiDPad as a predecessor for his best known-invention, the Palm Pilot.
