"Has it got a TCP/IP stack and internet browser as well? yes and yes"
OS/2 had both of those in 1994. More import is that it supports USB, which wasn't on OS/2 or Win95 in 1995.
I remember MIcrosoft OS/2 Server with LAN Manager (sold in 1989 after IMB and MS parted ways).
Is OS/3 the reason that NT starts at Version 3?
MS inflicted Win9x, not much more than Win3.x with the VFW & Win32s bundled optimised for gaming on businesses that would have been far better using NT3.5 or OS/2 Warp. A burden for them and business till XP (Win 5.1, Win2K was the unfinished Win 5.0). Idiots, though commercially sucessful, it was the source of most of the stupid design decisions and badly written SW on NT after 1995.
