That's cool that there's an IR solution. I plan to eventually own a PS3, and I'm sure it'll be my first BluRay player. I use a Harmony Remote that doesn't do Bluetooth. Hopefully by the time I get it, though, there will be other solutions on the market, since that USB dongle is WAY bigger than it needs to be. Better than nothing, though, and I'm sure I'd buy it today if I had a PS3.
BTW, has anybody else noticed that Nyko has been doing brilliant work this generation with their peripherals? They've been on top of their ---steaming pile of meadow muffin---, developing some really high quality, innovative stuff.
