Maybe this is a little over-the-top but...this would rock!! It would be really cool if the Sony NW-HD5 would be able to act as a external HD for the Sony PSP. Imagine much content you could be able to experience on your PSP without needing to use the Memory Stick Pro Duo (I'm not thinking music - I have the player itself for it - but pictures and movies). I don't know how many of you actually own a PSP but I'm sure you'll find this idea interesting too. Current Memory Stick Pro Duo biggest size is 2GB (hard to find and at prohibitive prices) and I have the 1GB one. (20 GB would be almost 10x the space, and would probably mean 40 full movies at good+ quality ~= 450 megs per movie, and/or thousands and thousands of pictures). The NW-HD5 is small enough to be a great companion for the PSP, it wouldnt be much trouble carrying it around with be PSP when you wanted to. Plus both are Sony products, both have usb ports so no huge compatibility problems, and my feeling is a simple firmware update would make this possible. Comments welcome!
