There are also a number of now defunct companies (like 3com, DEC, SGI) that produced network related chipsets for us in general computers.
The first VAIO laptop computers followed in 1997 with the US$2,000 PCG-505 "SuperSlim" model, constructed out of a four-panel magnesium body. [13] VisualFlow was a Sony program distributed in the late 1990s and early 2000s with Sony VAIO computers.
