Easy to read the cards, and I like the paperclip/magnifier idea to select more than one.
However, the implementation of tap-to-move is too smart, it automatically makes each move without confirmation - takes the fun out of searching for the destination yourself. With drag & drop, I find my finger gets tired after too much dragging across the glass. If I could, Id give it a 3.5.
