HI im a hobbiest game programmer and I came across this a few months ago and decided that the gpx2 is definetly something I want. First though I need to know some things. First I want to buy the 275 mhz version. Is the extra speed the product of overclocking or are they just faster processors and if so can I overclock it more second is wifi possible through usb or sd? third can i hook upa keyboard via usb for word processing etc. and also ihow is the sdk? I really look forward to playing my favorite retro games on this and programming games and possibly emulators for the community. and the features seem great . Thanx in advance!!!
