Not a damm thing, For years now I have had withdrawal from not using ClipFolio, in my mind it was the best clipboard used on a Mac. But now we have iClip and it seems to work great and behaves very well under the OSX OS, the one thing I am concerned about is will iClip become to complexed will it have too many and overwhelming features to make not worth having or using. I sure hope not. iClip has become a nice treat for the big cat........
