Noticed an old post from riddlerenigma regarding transporting an iMac 27" on an airplane and I was wondering what the final outcome was. The post was made in November of 2009. I´m flying from Spain back home to California and need to take my 27" with me. I will not check it in. UPS is too expensive (although if that´s my only option I guess I´ll have to do it). I was hoping riddlerenigma might have some feedback on his experience or anybody else. Does anybody have any experience transporting an iMac 27" AS A CARRY-ON? I´ve talked to my airline and they seem to think it would be ok, but the last thing I want is some security agent denying my passage of the computer... Thanks in advance.
