Yeah, actually what I have on my 8gb sd card could fit on the nand. But isn't the nand erased with a firmware update? Doesn't really matter. To each their own. I just find I don't need much space. I only play games that I have physical copies of though, or homebrew games... the only reason I pushed it any further was that it really depends on the person just how much space they need. I actually overbought with my 8gb card, but I guess that's not too bad either, as I'll always have room for some PSX games if the emulator gets good.
