MAKE pal C.K. Sample has a good overview of all the new things with the PSP Firmware v2.0. It looks interesting, and I’ll update once I have another PSP, otherwise (for me) the web browser isn’t really enough to give up all the homebrew games and applications. The coolest thing is the video/audio download and pictures via Wi-Fi, there’s a ton of projects and physical space stuff you can do with that. Link.
