Welcome back Cocoa. BTW, this product is hot. Fuck the looks, a big memory card and double life for the price of a memory stick? Now all I need to do is get a PSP. PEACE.
I'd definetly wait for a review of the product first but my initial thoughts are that the transfer rates are probably going to be on par with a UMD and will probably heat up the right side of the PSP.
It's probably just a modified compact flash hard drive with an adapter board to make it work with the MS slot. Those drives are pretty darned slow and sucks quite a bit of juice. Unless the data transfer is at least on par with using a memory stick then I'd rather just carry two sticks rather than bulk up the PSP. Too bad the slot isn't high speed.
Maybe someone will even come out with a battery cover that has a built in storage slot for a spare stick.
