Apple's emphasis on how it looks over function has always been a double edge sword. The lack of docking station, from both the hardware and software side, was the second most constant push back I received when asking about swapping the Dells out.

With TB ports and the like it could have been worked out to one cable instead of an edge connector, yet they seem to have zero interest in the business.

I have run Windows 7 even as primary at times but in the end went back to a Dell for work put an iMac back on my home desktop.
