I'd bet you don't care that it's attached to a Mac. I bet you don't want to switch OS. Which is understandable. In a couple of years, when Microsoft finally offers Windows as an ARM purchase, Linux is finally full-fledged done implementing support, and Apple resuscitates Boot Camp, I think a lot of people like you will look at Macs like the Mac Mini differently.

Just get used to the extortionate prices on things like memory and storage. Who wouldn't want to pay $200 to go from a 16GB to a 24GB configuration? Who wouldn't want to pay $600 more for the 2TB storage option? And forget about upgrading after you buy the computer.
