If I enabled me to run linux better on it. I'm all for it, would mean I could replace my computer, just my ps3 for all my needs.
if they get homebrew on the XMB then that would be ok too,
blu-ray rips might not impact it too badly
but a iso loader from a external hdd would ruin the PS3 imo like what happened to the PSP
no doubt compressed versions of games would come out most games don't take much more room then xbox games i believe eurogamer has said before
