Read almoust all the posts about the heat/fan issues as I want to buy the air. It got really interesting after macsimonwoo´s post in the "2nd core shuts down after 30min" thread (THANKS!!): "i think it is a known issue that has not been fixed. http://youtube.com/watch?v=juZW6eC9rAY&feature=related btw, i had this core shutdown too when i viewed youtube full screen..." So now it should be easy to analyze if it is a "flash-fullscreen issue", or a general video playback issue (bad cpu design?). All we have to do is: 1. The "no problems with video" crowd should try playing you tube videos fullscreen and check fan speed, etc. 2. The "My fan breaks speed world records" crowd should play non-flash videos and check...... I would love to hear that it is "only" a safari-flash bug instead of a bad cpu design..... Thanks.
