I never went the Sinclair route
My forays into early home computing started with a Superboard (6502/ROM BASIC), an Osborne 1 and a Jupiter Ace. The Jupiter was similar in size and general crappiness to the ZX81 but ran FORTH which meant you could actually do useful work with it. I've always thought that the history of computing took a number of wrong turns, one of the really bad ones being computers running ROM BASIC such as the ZX81 and the BBC; these types of machines taught a generation of people not only how to write code but also not how to program.
