Hey everyone, I'm going to be ordering a G5 Imac in the next coupld weeks and am debating on whether or not to get bluetooth. I dont really know too much about it though. Is this the only way to have a wireless keyboard/mouse with a mac? Also, what are the other advantages? I currently do not have a bluetooth phone or pda, but I there is that possibility in the future. If I didn't get the bluetooth now is it difficult to install myself down the road? Thanks, allison.
