114C is the CPU temperature, we have no idea what the surface temperature of the MBA is. These types of safety considerations are normally bread and butter considerations to any electronics manufacturer - there are plenty of guidelines and standards for them to reference and test to. That said, the safety limits are that - safety limits. They are not necessarily comfortable. I think the safety limits for continuously held metal parts (so a MBA laptop) is like 55C. I think the rough guideline on "comfortable" is usually considered sub 40C.
