The personal computing market of the 1980s is a cautionary tale about boom and bust in technology driven markets. It is a period in computing history that almost seems like a foreign country now. Acorn, Commodore and Sinclair are just some of the companies that no longer exist. Commodore is probably the most memorial loss. That said, the Amiga brand still lives on through a loyal user community. Even CommodoreUSA was revived before the new owner died.
It easy to see the parallels between the UK and US markets in hindsight. For example, the battle for market domination between Atari and Commodore mirrors that of Acorn and Sinclair.
