If anyone is interested, I found an intriguing visualisation on the history of computing... http://www.itrentals.com/historyofcomputing/ let me know your thoughts or any similar resources
Interesting timeline! Dad still owns some of those computers from the 1980s - he still has his ZX Spectrum and BBC Micro. Will have to get them out of the loft again and have a play with them again.
On a side note, does anybody else think that the Apple Magic Mouse is 'inspired' by the original mouse of 1963? You know... very flat.
