Feel free to mention any Intel macs being that we usually talk about those here as well. We're much nicer than the people in the Intel section that will tell you to upgrade the second they hear about your problem.
I was incredibly irritated on the Macbook Pro forum a few months back when I bought an early '08 15"(the last pre-unibody model). This is still an incredibly capable computer-I actually have two now, and the better of the two screams with an SSD in it. In any case, these models have known GPU problems and I was asking about reasonable temperatures to prevent GPU issues. I posted my temps, and someone asked if the post was even serious because my temps were "ridiculously low." Finally, someone who knew what they were talking about came along and as it turned out my GPU temperatures were flirting with "danger zone" although were running 3-5ºC below where problems are know to start to happening. Along the way, I was asked why I was even worrying about a 7 year old laptop.
All that said, I did just(yesterday) buy a mid-2012 15" with a hi-res Matte Screen. It put a BIG dent in my budget(especially after the watch I bought on Tuesday) but has been a machine I've wanted for a while as the last and best of the classic MBP. This particular one has a 16gb of RAM, a new battery(replaced under warranty) and is still under Applecare until January.
One last thing, too, of all the Intel forums I find the Mac Pro forum to be probably the most welcoming and informative. At least the "Classic" MP folks go to great lengths to keep their systems going and current. I actually see a lot of the same sort of passion and enthusiasm there as I see on the PPC forum. I was advised to run away from a 32-bit EFI machine I was considering(esp. for the price), but there are very solid reasons for doing that.
