pretty sure you're right.
So while I'll still play with the wifi, I bought one of these:

As the mini is sitting on top of the k200, this not only means I don't have to muck about with micro sd cards, but also that the normal sized sd slot can be attached to the k200 within easy reach.
I'm going to get one for the ctc i3 as well.
