If I have one complaint about my new 13" MBA, it's the heat when it sits on my lap. Do you have a solution? First, some numbers. I don't play games or run any CPU intensive apps. I took some measurements: CPU 75 C / 167 F My lap (with a meat thermometer between my MBA and thigh 36 C / 97 F The fan was running at 2K rpm I trust my meat thermometer. It has always served me right. While 97 F is about my body temperature and feels really nice on a cold day, it feels a bit uncomfortable to me on my lap. I tried putting a thin book between myself and the MBA and it felt much better. I used to use a laptop desk for heavier laptop, but the MBA doesn't need one in my opinion. But some thermal separation would be most excellent. Has any one used a MBA cover to keep cool?
