PSP Memory Stick Storage Device - UMEMD
Team Xecuter have released a picture of their new product, the UMEMD.

The UMEMD for the PSP (first release for the 1000 series) is a UMD shaped device that can hold up to 4 Memory sticks making storage extremely simple and convenient. Simply slot into the PSP as you would any UMD disc and away you go
As the market for PSP’s demands users to have multiple memory sticks storing their games or movies this simple yet effective product is the answer to that problem.
Shipping begins in 2 weeks - prices and stockists will be announced shortly.
Quite why this is only suitable for PSP-1000 units (ie PSP Fat and Heavy) I don’t know, as the device is simply a piece of molded plastic in the shape of the standard Sony UMD, that can hold muliple Memory Stick Pro Duo’s. It would appear to a fairly neat solution to the problem of carrying multiple Memory Stick Pro Duo’s around with you, although you still need to remove the device to either play a UMD game or movie, or to swap your Memory Stick Pro Duo’s round.
For those of you who exclusively use Memory Stick Pro Duo storage for all your gaming needs, this might be an ideal solution for your media storage.
