OP was asking about the PS3. Some of those, fancy ones, might not work so well or will lose features.
When looking for a KB for the PS3 you first have to ask, how much money do you want to spend and keep spending? Rechargeable vs. Wired vs. Battery.
Because the PS3 loses features and I don't want to keep replacing batteries, I have a wired one with a USB extension on it. The only problem is that the cord is across the room and you will trip over it many times, kids will yank it out, and anyone not you will 100% trip over it until you start warning them.
Also keep in mind that you will be using the KB to type only. You will be using the controller for Macros and Playing. You don't want to and can't use this.
