The PSP scene since the release of Hello World by Nem has been nothing short of outstanding, the amount of visitors this site and forums gets shocks me and the fact that for someone with a V1.0 PSP its so damn easy to get software working for testing and playing its great and the amount of releases means that as a webmaster in newsposting near on 24hours a day (not bad when some sites have 5 people doing the same job ). The scene doesnt seem to be slowing down either but is the scene the easiest to get into?
Looking at other Console Scenes you can forget about any you need modchips for or flashcarts etc so the next scene is the Dreamcast Emulation and Homebrew Scene which has near on 500 Emulators and Homebrew releases and once past the way of burning the software onto CD is a great scene.
The next console to think about is the GP32 with sites like GP32Xtreme and GP32 Emulation which have hundreds of software much like the PSP and a fantastic scene to go with it.
Finally the new kid on the block, the GP2X a console that even before its released officially, has a port of Quake, PC Engine emu and Amiga emu and embraces Emulation and Homebrew(check out our GP2X Sister Site)
All those 4 consoles are easy to get into but which is the most friendly you decide (comments below)
