LOL, well, I don't buy things to baby them. If it can't handle everything I throw at it without "blowing up", it's not worth my time, effort and $. Knock on wood, the Pro 2 with it's dual fans has been mostly able to keep up with the demand I place on it. Undervolting to a safe and reliable level just helps a slight bit more.
I'd really love the Pro 3 with I7, but there's way too many folks with issues for me to place my trust there yet. A few random folks might be insignificant but watching MS's support forums, reddit, and quite a few other places it seems far more than just a "few random folks". I'm getting the feeling MS might have pushed the envelope a bit to far for the I7 models. My wife's 3rd gen I7 pumps out the heat and it has large fans and heat-sinks, I can only imagine what's going on inside the super thin Pro 3 with the i7 and that dinky fan. I find it hard to believe that some engineer didn't think to put it under heavy load to see what would really happen.
Anyway, back to the subject, undervolting. Don't go overboard or you will crash. CPU/Graphics will undervolt quite a bit, uv on the memory too much and it's a sure recipe for a blue screen.
