I did a quick calculation last night to utilize the rate of inflation from 1985 until today and considering the original price of the Amiga 1000's on introduction of US$1295.00... and, magically, the number in 2010 US dollars looks like it would be very close to $2500!
Considering the cost of the RGB monitor, which was the only one that was compatible with the Amiga at the time, that number goes higher than 2010 US$3000!
On the other hand, it is not 1985 and one could say that the advantage of this new hardware in 2010 doesn't make a tremendously compelling argument.
That said, I am putting aside some money in an Amiga fund... :-)
