Ive had my air for 15 days... I just love it.... however it has 2 issues: 1.- It does not lie flat... small gap between rubber feet and desk... can be fixed if I put a business card between the two... I know it will get fixed because I ordered a See thru case from speck.... so I guess Ill be ok 2.- Ambient light sensor just dont work as my MBP works... the darn thing keeps turning the keyboard light on when theres no actual need for that. there´s no heating issues with it, no fan issues, no nothing, just those two things... Im a "prefectionist" (cuz im prefect ) and those two things kinda bother me... I called apple cuz there are no apple stores in Laredo TX and they issued me a RMA and sent me some fedex stickers to send the computer back.... The real question is: Would you guys return it and wait for a new one?
