First let me say that I do not own a MB or MBP. I have been looking at them trying to decide which to buy. Whenever I go to Bestbuy to look at them I have been impressed that they all feel so cool, given that they are always powered on, and there are always people playing with them. I have read in this forum people having issues with heat. I'm confused by this. Do these run hot? or Is this random? Thank you to anyone who replies. Btw, I use my laptop to surf, email, watch TV and movies. That's pretty much it. Do you think MB or MBP fits the bill or should I buy an iMac? Thx again.
