Re: ' by 1998 there was no actual need to buy a mac for DTP. NT4 was excellent'
In 1988/89 the Mac revolutionised the professional print and design industry.
IIx, II fx, IIcx, I remember them well - even the dinky little Classics and SE30s could do useful work for some.
Overnight commercial typesetting companies went bust.
Advertising and general publishing then got on board and by about 1994 the reprographics industry was also chewed up and spat out.
Windows was not a viable replacement till 2000, if that, and even then every design professional would laugh contemptuously.
Lisa led the way.
Disclaimer : I've not used a Mac for nearly 20 years.
