I'm looking to get a wireless keyboard and mouse to use with my PS3 and PC that is setup side by side on my table.

If I have both the PS3 and PC turned on at the same time, is there any other hardware that I need to get to be able to switch back and forth between the PC and PS3?

Also will any bluetooth wireless keyboard and mouse do? I'm not looking for the best; as long as it works. I was initially planning on purchasing the ones that are sold by Dell.

Appreciate any information or suggestions.

Thanks
