I kind of feel like applicants with offers have the right to take their time in finalizing their decisions (and I'm on wait-lists, for what it's worth), and that the OP comes across as a bit self-centered. Also, I received an acceptance yesterday, so it's not like admitted applicants are necessarily sitting on acceptances that they've had for several weeks.
More importantly, can anyone speak in more concrete terms to the issue of better fellowships leading to better fellowships further along the PhD track? It seems somewhat unfair to award fellowships based on who already has fellowships (rather than on some other competitive basis), but I basically have no idea how graduate programs work. Also, is whether or not someone got some random "prestigious" fellowship at whatever program they went to really going to be a significant factor in terms of getting a teaching job (especially relative to factors like what program they're getting their PhD from, the strength of their dissertation, etc.)? It seems like kind of a minor issue to me, assuming that you are otherwise performing.
