^ OK, valid point about the touch screen.
However, with the same lens mounted, the K-01 is always going to be about the same size as the NEX (haven't looked up specs but you can't get around those 45.46mm of air, whether it's in the body or an adapter). Yet the NEX can be made much smaller if you go for RF lenses.
K-01 makes sense if you're invested in AF lenses. If your legacy glass is MF, all it does is lock you out of other mounts.
