How Hot is Too Hot? Why? How?

The laptop computer felt hot to touch.  How hot is too hot?  That basic information was not evident with a Google search.  Then, a bright idea.  Yesterday the MacMedia email had arrived with the clever heading, "Geek Goods for your Mac Daddy!"          We had purchased the MacBook Pro at the MacMedia store down in Peoria in September.  Who better to call?  A helpful guy, Rob, didn't seem in too big of a hurry to chat. I explained, relating some of the temperatures I'd noted from iStatPro widget.  He explained the range of temperatures, reassured me that mine were OK, "That's why we don't call it a 'laptop' anymore."         The helpful widget is here.
