I Use Constantly

Much better than other clipboard apps I have used. The IAP adds some significant features, particularly synchronization between devices. Very useful even without the IAP ( many free apps wont do anything without an IAP). I bought the update because I find the added features very useful, especially iCloud sync among devices.

A PC program would be nice. It already syncs with MACs.
BTW, macstories dot net has an excellent discussion of all the features as used by a professional writer.
