this one is CONFIRMED by myself to work:
Microsoft Wireless Media Desktop 1000
bought it for 35 dollars at staples, plugged in the receiver and turned it on, everything lit up and started working immediately.
it is very slim and light compared to the other keyboards i have used, however, this is my first wireless, and didnt want to step into the ultra expensive bluetooth units
It's too bad this list is showing up so high on the search engine results because it's really out-of-date.
I have had no problem connecting the Apple mini keyboard (aluminum style). The PS3 discovered the keyboard, prompted me to enter a code and paired it. It even identified it as "Apple mini keyboard".
I have teh Gear head wireless mouse and keyboard. It works great on my PS3. Its not bluetooth but the one usb port taken up is worth the price drop from bluetooth to wireless keyboards.
actually the apple blutooth keyboard works but its a pain in the ass
if the batteries die i found i often have to resync, or if the system freezes the sync also messes up
so nvm leave it in the **bleep** list
