“Why do you need *nix” – “because I have *nix” is a bit of a tautology, is it not? (-:
Nope, unless the Windows team – that need Windows to manage their Windows servers are also tautologous. I’m much more efficient managing *nix through *nix, in the same way the Windows team are with their work. Can I do it using Windows? Possibly, but keeping copies of Linux on other machines to use for management due to the size of the estate.
I’ve never had a problem with VNC, used to use UltraVNC to connect to all manner of things. Though when I have to remote manage Linux boxen I’ll use PuTTY rather than VNC.
I use PuTTY to connect to other Linux boxes which I use as a hopping point for the production Linux/AIX/Solaris/HPUX boxen. When you’re talking thousands of servers you can’t log into each, you need a good regime with trusted servers (note: not windows). We use VNC for oracle/TDP/SAP installs, but that again requires more Linux machines/VMs for somewhere to VNC into, especially with firewalls.
Windows has its place but it is not the only thing out there. I could happily do my job without Windows. Everything I need could be done through a web-based interface, including office documents.
And windows 8 is still poo! 😛
