I may not know my history very well, but I thought NT was based on OS/2 
*and* I thought OS/2 was Microsoft's first true windowing OS.  True, it 
was a joint deal with IBM, but Microsoft was heavly involved.  If true, I 
suppose if anything OS/2 was a stepping stone between VMS and NT.  Anyone 
know more?
