My PS2 has finally died, and I am looking to hunt down a PS3 60GB for the hardware backwards compatibility. I've located a few for ~250$. Since I've never really used a PS3, I have a few questions. First, the one I am looking at the most says it comes with the 2.7 firmware. If I upgrade the firmware, will that completely remove hardware backwards compatibility for PS1 and PS2 games? According to Wikipedia all firmwares can play PS1 games, but emulation for PS2 games seems to be a bit less clear.
Second, can I replace the internal hard disk with a custom one (something like a 1tb hitachi travelstar)? I've found reports that the hard disks are user upgradable on wikipedia.
I'm just trying to figure out the current "state of the union."
