A woman whose husband leaves her alone frequently or for long periods to engage in a usually specified activity, in this case an iPad. An iWidow differs from a widow only in that her husband is physically present and always takes the good chair, but is otherwise thoroughly absent in every way.
iWidowhood is a condition often characterized by the repeating of husband's with no response, making requests of husband that go completely unacknowledged, and a generally sour and neglected demeanor.
