I don't have a problem with the PDair extended battery case. It is similar to my Rhino case but holds the PDA with extended battery pack. I would assume they sell other cases on their online site. I just ordered the case, so I cannot comment on ordering multiple items. I have seen a lot of crappy styli out there and only plan to order them directly from Dell.
Those screen protectors are not easy to apply right, even with the little credit card thingy. I still manage to get a small speck of trash or two when applying mine.
