Sony pisses me off. I can buy an 512 megabyte SD card for my PDA or digital camera for like $40, even $25 in some places with rebates (which is playing roulette at it's best). But for my Sony PSP, 512Meg Memory Stick Pro Duo cards are, at their very best, $70 shipped. Flash is flash, this one doesn't cause world peace, nor does it provide any sexual satisfaction. Sony, you deserve a beatdown.
