Carl,
This month's edition (Sep 93) of the Computer Shopper has an excellent
side-by-side evaluation (cover story) of WinNT and OS/2 2.1. It talks about
both systems and their supposed potentials including backwards compatability,
(a potential problem w/Win NT). Their relationships with 3DS3 will still have
to be confirmed here though.
Good Luck,
Chris Truty
