[quote name='fujishig']I had to look up pro duo prices to see what you were talking about. Wow.
A few weeks ago I bought a 16 GB Memory Stick Micro for my PSP Go... and it seems like the micros (25 to 30 bucks for 16 GB) are much cheaper than the Pro Duos (44 to 47 for 16 GB), and I have no idea why. I have no idea what the NGP is going to use, but I don't see why you can't just buy a micro 16GB and an adapter for much less than the price of a Pro Duo 16GB on Amazon. Is there something wrong with the adapters or the Micros?[/QUOTE]
Same here. I bought a 16gb m2 Memory Stick + a MS Pro Duo adapter for ~$26 (including shipping) from amazon. I have both a PSP Go and a PSP 1000 so it's a win-win situation if I decide to expand my memory capacity on either of the PSP units. The m2 Memory stick works perfectly on the PSP Go, and when I use the adapter it works exactly the same way a Memory Stick Pro Duo would in my PSP 1000.
