Back then, the alternatives were a typewriter or hand writing everything. Since I could touch type, hand writing was slower and neither alternative allowed for the kind of easy editing that is enabled by even a primitive word processor.
But yeah, mostly I played games on it. It was a great gaming machine for its time.
Like: For $595 you get what nobody else can give you (and it's only) for twice the price.
It's also possible that the ambiguity was intentional.. Ad copy is an art and it did compel me to read all of it to unpack the meaning. Though thinking this through I would assume that everyone interested in computers at the time would know what the prices of other products were so the $595 would immediately be understood as very cheap in comparison
It's not until I scroll down to the pricing table to see what they really mean is their machine is half the price while having more features than the rest.
