' by 1998 there was no actual need to buy a mac for DTP. NT4 was excellent'
No true. The reason is Windows lacked color management until Windows 2000 (and even then it was an initial version not yet fully smoothed). NT4 was excellent for many tasks, but not graphical ones. It did have also a far older version of DirectX compared to 95. It required different graphics drivers than its less powerful cousin, and their quality varied.
Fonts display, management and availability, native PostScript support and other features gave an edge to the Mac, and Windows took years to close the gap for professional users. And the whole sector soon was running on Macs. Microsoft was interested in the generic office space, not so much about specialized sectors.
