Hey, I'm new on these boards and will soon be the proud owner of a Macbook Pro. I just had a quick question about how hot the new systems get. I can see myself using my computer all over the house...will I need a desk to put it on or will it be ok to put it on my lap/other fabric? I really don't want to cause it to overheat and cause strain on a brand new system. Any info/experience is appreciated.
