The Compaq Contura Aero was popularized as a line of computer handhelds produced by Compaq Computer Corporation. It was succeeded by the iPAQ line. The Aero name was first used for small sub-notebooks computers that Compaq produced in the mid-90's, the Contura Aero 4/25 and 4/33c.

Early Subnotebook

The Compaq Contura Aero 4/25 and 4/33c were among the earliest subnotebook computers that acted as a precursor to netbooks. They were released in 1994 and originally ran MS-DOS and Windows 3.1. They were also able to run Windows 95 after its release in 1995. They were part of Compaq's Contura line of laptop computers but were smaller.
