This is more of a terminology question...
I'm developing an occasionally connected application that will run on a tablet for clinicians or field service workers but I'm struggling with what this type of computing is referred to. Mobile computing as connotations of a phone app. Whereas our clients may be occasionally at their desk. Microsoft uses Smart Client a lot, but I'm not sure if that best describes this scenario or is the common term for this kind of computing.
Is Tablet Computing a bit too blunt for you? It's certainly a well-known term, and it seems to adequately describe your client's use case.
