so, this screenshot is a mac osx style operating system that is made for the psp!? I'm about to purchase a PSP and i'm doing my research before making the investment. If this screen shot is an OS that I can download and use on my PSP, then I'm buying this baby. I've basically been wanting to use the PSP for presenting videos, seeing as I'm a digital media production student, and would like an easy, portable way to show my video to clients. I think the PSP does this, plus gives me the options of using other cool programs and such...but I still need to gain some knowledge on the PSP and homebrew apps and what not. What are the limitations, advantages, etc? And how easy is it to downgrade/upgrade to be able to use my PSP in new ways? If anyone can lead me to a site that can tell me all things about the PSP, please send me a link. I'm looking forward to playing with my PSP! Just got the 3G video converter to convert my video's to PSP playable formats without hogging too much space. ALSO - does the psp have a built in hard drive? or does it only work off of memory sticks? Let me know please, I need to dive into all the info I can get! So far, this site seems like the place to start on my psp adventures.
