I got my refurbished mini in the mail on Friday. I played around with it this weekend, but I think I actually prefer my Macbook Air. My mini just seems slower for some reason. It lags on just about everything. Maybe its the HDD Mini vs SSD Air I'm seeing? But anyway, I am returning it for now. I will wait and see what Apple releases with the next gen Mac Mini or maybe even get an iMac. But my main question is, should I boot into the recovery partition and reinstall OS X before shipping it back? Do I need to do any security options or just install the OS? I only installed one App and set up my email. That's all I did on it. I never returned a mac before so I not sure on what's recommended. Thanks
