For me it was one over whelming reason, I couldn't play my UMD games on the system. There is no way I am going to go spend around $1000 dollars to get digital copies of all the games that I already own. If Sony had come up with a way to copy the UMD game on to the psp go internal hard drive I would of bought it and started purchasing new games digitally. That's why the psp go failed.
