I m afraid this topic is not a joke, here it is: " The company also noted a problem with using the MacBook Air for prolonged periods. According to that note, also now removed from the site, after long periods of use the computer may become sluggish as it attempts to protect itself from overheating by shutting down one core of the CPU. Apple also said that in extreme conditions, the MacBook Air may reduce the clock rate of the remaining core. The company's recommendation was to move the computer to a cooler area or use a cooling pad to dissipate the heat, but this note was also removed from the site." So my office table is not cool enough apparently, i should open a window and hold it out of the 14th floor window for ten minutes every couple of hours?
