I have the MMP, and a 4 GB compact flash card. The MMP is ok, but I want more compatability so I want to get the SC or M3. The only thing that is bugging me is that I do not know how far these suckers stick out form the system. I have a NDS Lite. I was wondering how far they stick out because when i listen to music, I put the system in my pocket and the MMP doesn't stick out as much, but with the M3 or SC it looks like they stick out much more. Does anyone know how much more they stick out? Is there an adapter that folds to the back of the system like the MMP does so it doesn't stick out as much? Have pics? Any suggestions on which to get. Also, I know I need the Passkey, does that work with both the M3 and SC? I want to stick with my CompactFlash card, so don't suggest the sd mini or lite or anything like that. Thanks
