I prefer a keyboard that when you hit somebody with it, they fall down and *stay* down. Model M. :)
This is why I have a small stack of that exact model. When the revolution comes and we all have to welcome our new robot masters, I'll be hoping that my work in IT/IS will curry me favour with the new world order, and if not, the stack of keyboards will double as self defense weapons. ;)
On topic: After having dealt with various KVM's, Dell DRAC, Hp iLo, Supermicro IMPI, etc, I would much rather use a remote access system like the iLo or Supermicro's IMPI stuff. Less cables and, usually, a much better setup. The Dell KVM's we have at work are horribly slow, and the java that connects to the console is twitchy at best. The stuff SM uses is better, but still not amazing.
I do have to say that the .NET console the HP iLo's have as an option is surprisingly good, especially in comparison to the previously mentioned stuff.
