The iMSO-104 works better on an iPad than an iPhone becuase of the bigger screen. I haven't tried it on an iPad mini.
Brian Dipert (along with Paul Rako) did a review of this over on EDN. Looks like a reasonable option for anyone whose applications are within its capabilities and who needs a portable solution, or just doesn't have room for a benchtop model.
Scopes, especially the mixed signal ones, are in a position to pick off some other test equipment commonly used. Anyone using a scope for an app today that they needed a specialized piece of test equipment for in the past?
