I'm not sure there are any Bluetooth controllers for any OS as of yet.
I was just hoping for HID support in Remote Buddy so that we can map buttons on a USB/Wireless controller(HID compatible) to commands in the Application via Remote Buddy's wonderful GUI.
So, far that's the only thing that's keeping me from purchasing a copy.
Microsoft is planning on releasing a USB adapter for the current XBOX 360 controllers(probably won't be HID but there are other options http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/OsxDriver). But, they are also working on a new controller that works with both PC and XBOX 360 wirelessly... could be BlueTooth could be HID USB... nobody knows yet. If all else fails though I have a USB adapater for Playstation controllers that works really well with games and I bet it would work great with OS apps.
P.S. The Amiga rules. I was one of the few Americans that actually appreciated the machine. I had an A500 that I soon upgraded with a 52MB HD($500) and a half MB chip RAM. Later I picked up an A3000. I loved my Amigas.
