I was look for a nice case for my Palm m500, and I though this was it. When I received it though, I discovered that the "rail" intended to fit the channel in the left side of the pda is entirely too thick to fit! It DOES fit the channel for the stylus, if you don't mind having the m500 pda in there upside down, and have no place to store the stylus. Add to that the fact that even with in the case the wrong way, the case is actually too narrow for the m500. I was really disappointed. If you are looking for a nice case for your m500, this is NOT it!
