Oddly enough, I bought my PS3 to play PSOne games. My memory cards no longer functioned so I had to go with a reaally expensive memory card, known as a PS3... heh. Speaking of which, I should grab some PS2 memory cards before they all vanish off the planet as well. Not being able to replay PS2 games would be rather annoying, unless the PS4 lets you download them. I have no interest in paying for them again though.
