Here are a few IMP points regarding heating issues:-
1. All sandy bridge cpus run cooler than there first gen cpu laptops (eg XPS 15 old and XPS15 new).
2. The main reason is the dual GPU's as the intel 3000 series gpu is good enough for most tasks and it runs really cool compared to the other dedicated GPU (ATI or nvidia).
3. So 6017 and xps15 runs at more or less same temp when on intel gpu.
4. However when on the dedicated GPU say while gaming, 6017 heats up quite a lot.
5. But a good cooling pad really helps get the temps down to i7 with HD6770 acceptable limits.
6. I have played for an hour continuously and havn't faced any shutdowns due to overheating.
7. If you are a gamer,
a. Go for it IF you are going to play games with a good cooling pad and in a cool room preferably with a ac.
b. Dont go for it if you will be playing it without any cooling pad, playing in a cool room helps but is not completely necessary.
8. There is no heat build up anywhere on the keyboard or touch pad or right side of touch pad, it is only on the left side of touch pad...
9. (Joke) There is an upside to this, laptop can be used for its heat in cold winters
