Vista wasn't then again VMS 6.1 wasn't that mature either... But VMS had the advantage that it and the processor (VAX) that ran it were designed in concert. x86 architecture and Windows are more a case of being cobbled together iteratively and separately. -- "Worry is a misuse of imagination." -- Some Guy Called Dan Zadra
