I'm running Logic on a Mac Pro laptop and whilst it does heat up quite a 
bit, I have never had a problem with it. My own rule of thumb for how much 
to spend on a piece of computer equipment is this: 

the longer you are going to keep it, the better spec you need in the first 
place, because you always need more memory, processing power, hard disc 
space etc than you can ever envisage. 

I have a related question: I bought my laptop primarly for logic - would I 
have been better to by a desktop. I am specifically thinking of connectivity 
and sound card issues
