I've used Windows at work this month because I do programming on that platform but since moving house, poor old Octogig has sat in the corner and has not been powered up at-all. I've used Apple devices, the Mac Mini, the Air and various iPads and iPhones for all my computing needs, even writing a quick app in Xamarin Studio to fiddle with some graphics.
This is the first time since the late 1980s that I have not had a Windows PC running in the house!
I even copied my Windows virtual machine onto a hard drive and deleted it from my macbook because the 63 gigabytes it was taking up was hogging up the main drive which only has a 120 GB capacity anyway.
Running absolutely everything on Apple stuff is a bit strange. Thinking back though, I remember trying to use the Mac I had some years ago and it was no use to me at-all. Perhaps times have changed, or maybe I have.
