Linux ServerWatch writes about the slow but sure death of UNIX by the onslaught of Linux and customers moving from older proprietary UNIX systems to commercially supported open source enterprise Linux distributions. "Linux does have one killer feature that is driving the switch: lower cost. Many companies are discovering Linux to be extremely attractive from a cost perspective. Take the experience of Sabre, a travel company that replaced Solaris with Red Hat Enterprise Linux (RHEL) running on x86 machines, resulting in lowering costs 90 percent (with a three-fold speed gain to boot). These potential cost savings, which include hardware maintenance costs savings, are not to sniffed at."

1) Solaris is no longer propietary, and unlike other historic unix operative systems, it's actively developed.

2) UNIX does have some features than Linux doesn't have — single-system RAS capabilities and the ability to deallocate failing processors online, for example."

Linux has been able to deallocate failing proccesors online for a long time (I can find commits about cpu hotplug from 2004), see /sys/devices/system/cpu/cpuX/online
