Mac OS X is my primary OS. I also have to run quite a lot of VM's. I have been running eOS since beta 1. It's by far & away my favourite Linux distro.
Whilst some of the designs are similar and may offer some familiarity to OS X users initally. The user experience is very different and has clearly been well thought out and crafted. My only gripe is the time between updates/releases otherwise I'm a happy user of OS X and eOS.
