This is my first PSP, haven't had time to open it yet. What is there to know for an absolute newb? I'm assuming the first step will be to configure my WLAN and then register it with the PSN account of my choice? (Pretty sure I'll go with the UK account - best selection of games for the 10-free-games offer.) Then download some demos, I guess? While I wait for my download code for the 10 games? Does Media Go work on a Mac? How easy is the syncing/managing games with the PS3?
