A quick, objective question to the group here. I've been saving my returnable money to replace my 2005 PowerPC. I'm on the bubble, looking at the quad 2.93 and ready to place the order. But I also see that the lifecycle of the current offerings may be coming close to an upgrade, though I don't know what that might be, or when it would drop. I'm not "in desperate need" of an MP right now, nor am I in an OCD frenzy about the latest technology. I'm only looking for any educated advice, or information on what to expect in the MP lineup. Should I buy? Or should I wait? That is indeed the question. Thanks.
