The real question is whether it makes business sense to learn Linux/Unix or not. The difference in support price from Microsoft, as opposed to the support from Red Hat, is not that great and Windows admins are much easier and cheaper to find than their Linux/Unix counterparts. That is the logic to follow if your choice platform are COTS Intel/AMD machines. Windows OS is in many respects better than Linux. Having said that, I'm a long time Linux/Unix aficionado who has had Solaris/x86 v5 on his desktop PC and who has paid for the original StarOffice license because I didn't want to use Windows. Even this is written on Fedora 19.

I find Windows with Cygwin installed to be quite a good approximation and very usable. Windows 2008 R2 (server variant of the Windows 7) with Oracle performs as good as RH Linux 6.4 with Oracle, or even better. With 64 bit chips, the windows multi-threaded architecture becomes an advantage becomes it's much cheaper than the Linux/Unix IPC and multiprocess  architecture, primarily because no device drivers are needed to share memory so pins, mutexes and latches are much cheaper on Windows. There is also the question of SCSI emulation which significantly increases the number of interrupts on the Linux boxes.

Of course, the logic changes dramatically if there are real office mini computers to support, like AIX or Solaris. Clustered PC machines cannot even approach the performance of a true servers like IBM Power 795 or Oracle T4-4. The price would also be prohibitive, primarily because of the Oracle licenses. A Linux admin will pick AIX or Solaris in no time at all, because they're very similar, while a Windows admin will have much steeper learning curve to go through.
