Need a wireless clicker for keynote presentations

[OldManJimbo]

Any suggestions for a remote clicker? The little clicker that came with my Mac requires line-of-sight and thats not always convenient. I'd prefer a Bluetooth unit, but USB is OK. I just want something simple that will advance slides from where ever I am in the room.

You could use your mobile phone, if it has Bluetooth. Some Sony Ericsson were able to control the Mac I have.
