I know there's probably already 100 posts about SGPStore, but I wanted say that if you are looking for a solid, well made, well cut skin for your Mini, look them up.
I went down to their offices in Los Angeles today. Very friendly. They showed me samples of all the materials I could choose from, cut the skin right there and then installed it for me while I waited. Took less than 20 minutes and it looks super clean. (Pictures when I get home from work.) I went with the Dark Black Leather. I contemplated the Carbon Fiber and was impressed with the quality, but they had one of their own laptops with the black leather and it looked super clean.
For those of you looking for skins for your Mini 12, I'll be bringing mine down to them either tomorrow or Tuesday for them to get measurements from.
