Contacts is implemented like this. At least it was a while ago, I don't know if that is still the case.
Still, yes, embedded activities it pretty cruddy. One of the goals of Fragment is to provide a better solution to replace it. (For some perspective on where embedded activities came from -- early UI designs for Android were very tab-oriented, and we were looking at tabs as one of the extension points for applications, allowing the tabs to host activities from other applications. Ultimately though the UI moved away from that, and we thus never implemented the (complicated) support for cross-process embedded activities and probably never will. So embedded activities uses the heavy-weight activity abstraction on the theory that the activities you host could be in separate processes, when they actually can't. Fragments provide a better API because they drop the pretense of these things being so separate.)
