I've seen people commenting on how hot their Surface gets. I have one of those Black and Decker Thermal Laser Leak Detectors and decided to check out my Surface using it. Now I'm not sure that this is the BEST way to get the temp, but it's the best way I can think of with what I have. The Laser is supposed to read the temperature of surfaces which seems like exactly what I would want. I started my Surface playing a TV show on HULU PLUS and let it run for about 20 minutes or so and took some readings with the detector. I got various readings on different points on the back of the Surface. Everything from 100.2 to 103.8 depending on the location, naturally it's hotter over the processor. So it certainly does get toasty but not hot enough to burn anyone. Possibly it might get warmer if it ran longer. Maybe some games might tax the processor and video unit more than just a TV show, I dunno. Also, I had it sitting on a table using the kickstand so the back was semi-open and air could circulate beneath the kick stand. The < might > lower the temp a half a degree or so, I suppose. Also, I didn't take any reading on the area below the kickstand. Only on the top half.
