Our PSP Fanboy brethren seem to be rather offended by the idea, but while this new "PSP Double Expand Memory Converter" isn't quite the slickest solution of all time, we're kind of liking the dual memory slots it offers up. The adaptor plugs into your regular Memory Stick slot, attaches to the back of your PSP
, and offers up a pair of SD/miniSD/MMC/Memory Stick slots. It's also dirt cheap, at a mere $16.77 US, so if you can get over the clunky method (which is diagrammed after the break) then you can, um, do whatever you'd do with two memory slots instead of one -- for cheap.
