This not a bad case, don;t get me wrong. I just found that it was not the most user friendly. The Exspect Leather Case for the PSP is great for storage and transportation. It is protects well and has plenty of storage for UMDs.
However, I have one major point to make that you should consider before buying this case. Don't get carried away with buying the first thing that you see, just because it is listed higher in Amazon, it doesn't mean it's the best solution.
My point, you have to take the PSP out to play / use it!
Since I bought the Exspect case I have seen others on Amazon that allow you to keep the PSP in the case and still play with it. Take a look at the Noreve Tradition...
