My first computer was a ZX 81 – cost £69.95 (assuming Wikipedia’s correct; I can’t remember!) That’s c £236 (This is Money) or 0.3% of an average house (House Price Crash). Came with 1kb of memory (expandable to 16kb) – Operating System & Keyboard inc; monitor required (monochrome output).
The Raspberry Pi goes on sale today … for £21.60 (0.01% of average house [does that say more about cost of houses or electrical components, one wonders!]) – you get 256mb memory, though you do have to add a keyboard and Operating System, as well as the monitor!
Me: I’d have one on order, were it possible to get through to a website!
