I'm not going to argue about pricing, I'm just taking some exception to this (emphasis mine).
I used a Quad G5 alongside a 2.3DC G5 for three years. You probably knew that as you've been here on MR three years longer than I have. Anyway, any of my Macs or PCs that are powered-on stay that way. I don't turn my computers off and I don't allow them to sleep. I allow monitors to sleep, but that's it. So, with the exceptions of rebooting or powering down because I need to remove/add/replace parts or physically move computers, all my computers are running full power 24/7/365.
In all of this, do you know how much my electric bill went up during the years I was using the Quad and the 2.3DC? $20 a month.
Now, if $20 a month additional on your electric bill is a deal-breaker, you are either single or counting your pennies (or both). But compared to my 5-ton A/C unit (which broke), and my five portable A/C units that I've had to use since, this is nothing. My electric bill hits north of $500 a month during the summer. I live in Phoenix, Arizona. Do you know what's causing my electric bill to spike so high? It's sure not computers being left on sucking a lot of power. You know how I know that? Because during the winter my electric bill hovers around $100. For a two-story, three bedroom house.
So compared to my air conditioning, this is nothing.
Now, I use a MacPro 5,1 (a 4,1 updated). It too is left on 24/7/365. Between my 5,1 and my G5 Quad, which 'old tech' is doing the most sucking of power? Hint: it's NOT the MacPro.
Yes, compared to a much more modern Mac or PC, my MP is drawing a lot more power. But, if the most power hungry Macs ever made drive up an electric bill by only $20 a month, is the power draw of an old MP 5,1 really that much of a concern?
I didn't lose any sleep with what the Quad and the 2.3DC drew (plus all my other computers), I don't lose any sleep over what the MP draws either. This is really a non-argument to me.
