i got my GP32 FLU just after GPEngine released. Spring 2002? have i really had it that long? wow...
watching the scene for maybe a year and change before that (i guess since GP32 was pretty new). anyway, i have been watching the GP2X scene with a fairly keen eye since, as well.. and some guys in my office have picked them up as well, but a few things have kept me from adopting. batt life, joystick (usual) but most of all $$. Between my GBA micro and GP32 (with DrMD and Mame) it feels like i am already very covered for games. If/When GP2X gets literally "perfect" SNES emulation (to the degree and ease of use as there is with DrMD) then I'll probably think about it more honestly, but in the meantime I am more than happy with what I already have.
If GPX Kids (or whatever it's called) isn't retardedly small and they manage to get GP32 apps running on that thing then I might sign up for that instead. I like GBA Micro-sized devices the best, it seems..
