I've seen this addressed earlier re the heat the MBP emits from the bottom. Users (including me) have complained that the heat is actually great enough to burn their laps. Appple's reply is that these are not "laptops" but "notebooks," and should not be rested on your lap. I accept that and put a pillow or a laptop desk on my lap when using it that way. A bigger problem, though, is that I am getting nerve damage in my thumbs and the pads below them from resting them on the panel below the keyboard while typing. After all day on the computer, I often end up with real pain there from the heat. I ran the "temperature monitor" app on my mac to see if it was indeed running hotter than it should be. The hottest temperatures are at about 140 degrees F - which seems pretty hot, but there is no recognized "upper limit." I asked someone at the Apple Store, and he said the computer (at least) was in no danger until it hit much higher temps. What about me? I guess my question is, does anyone else have the same issue with hand pain (in addition to lap pain) from the MBP? If so, has anyone gotten any idea from Apple that they recognize this as a problem?
