When we posted about the announcement of the slimmer PSP yesterday, there was one small detail hidden in the specifications sheet that we missed. This new PSP doesn't just sport a slimmer body, but also: 64MB of RAM compared to the previous model's 32MB.
How will the RAM be used? Sony says it will help to speed up load times of upcoming PSP titles. We're also guessing the internet browser will be retooled to take advantage of this extra memory for dramatically better cache performance.
