Thanks for the reply.
I guess I should have been more explicit. The Dell case is simply an open-ended stiff pouch that the pda slips into. I like it because I like to use my pda without anything attached, and I can slip it into the case to protect the screen when I'm not using it. I have seen some similar generic pda cases, but they all have a flap on the end that adds bulk. The Dell case is custom fitted, so it adds little to the overall size. Also, the pda slips easily in and out of the case, unlike cases where the pda is intended to stay in the case.
