Bluetooth and PS3
Someone I know (Mole from HDBlog.net) recently bought a PS3 and also got himself a remote for the included BD player. He noted to me that it shows up as controller number 7. He also asks “Does this mean we are restricted to 7 bluetooth devices? That could add up if headsets, dancepads, keyboards, mice, and microphones all take up slots.”
Personally, I don’t think that this is much of a problem. I think it’s unlikely that you’ll be using more than 7 Bluetooth devices all at the same time. And that’s the only time when this could become an issue. Because the slots aren’t hardwired, you can activate a Bluetooth device and if a different, now inactive, device had used the same slot, you don’t have a problem.
