A:Answer It got pretty hot when I was downloading VisualStudio. I can't explain in degrees, but I kept my palm under the left side since it was COLD in NY in my bedroom. It helped me to warm up my hands..haha. Since Its aluminium/metal case, it cools down pretty fast. On normal browsing, 3 IE windows, 4-5 Chrome windows, Had visual studio open and coding. It was very slightly warm. I guess it only heats up to that degree when you are downloading, installing, and doing photoshop/video edits. Average, normal usage, it should be very light warm. Also it could have been that I had it charging while downloading VisualStudio. Overall you shouldnt experience that unless doing heavy duty lifting.
