A Tiny But Powerful Raspberry Pi

Here is a Raspberry Pi . Not very edible you may think but very powerful considering it's size .It weighs only 82 grammes and has the following dimensions. 15x10x4cm .It has 1GB of RAM and speed of 900mhz.
Compare this to BABY ,the first computer which weighed a tonne, & was 17 foot long and stood 7 foot  4inches high. It had a speed of 100kh. The Raspberry Pi is 9000 times faster than BABY. These amazing tiny computers are astonishing in their uses .
 In MOSI today and  looking at the huge and astonishing displays of electricity through the years I read the following :-
By 1939 only 67% of the UK population had electricity and for most of these  it meant lighting .Gadgets such as irons were plugged into lighting sockets ! The average household could not afford many if any gadgets .
Now it is very much the case that 99% of houses own a vast array of electrical goods  and at least one laptop or pad . How times have changed and BABY showed us the way .
