I was in on the early heady days of home compution, starting with the Sinclair ZX, Acorn's Atom (1978), the BBC Micro(~1981), the Archimedes (~1988), then my Apple (1996). In those days there were many magazines especially for the home user, and people marvelled at programming to convert decimal numbers into Roman numerals and other exciting tasks. I was recently reading an article on how to make a woodturning jig. The plans dated 2002 were accompanied by a statement that the file is 450 KB in size so it will take several minutes to download! It took me about a second! Assuming 2 minutes, that is a speed rastio of 120/1 = 120. Have home computers speeded up by that factor over the last 14 years? Seems credible.
Acorn (their premises in Cambridge in 1978 were the other side of a pigeon-strewn yard) is now the world's biggest maker of mobile phone chips!
