Hello Mac OS X, Linux stay for a while

A week ago my new Mac Mini arrived and since then my main desktop has become Mac OS X. It's my second Mac, the first one being a PPC 6100 which was later upgraded to a 6100AV


This doesn't mean I won't be using Linux or any other form of UNIX-like OS's besides Mac OS X. My Worklaptop is still Linux-based and a VM with Linux Mint has already been installed.
I'm busy with my prepartions for CCNP Route and GNS 3 isn't ready for Mountain Lion (yet) I end up with a Linux machine anyway :-)
