Never having owned a laptop before (always used my Dell laptop at work), I bought an Ultimate 13' MBA two months ago.. I am in love with it.. amazing machine. I opted for the 13" over the 11" as I wanted more powerful graphics and a bigger screen... This weekend I was flying on personal travel (coach class) and lo and behold.. the MBA was really not that useful in a coach seat.. The height of the display was just large enough that to open the clamshell at a decent viewing angle required me to basically put the screen into the little recess that holds the table tray.. I could just imagine the person in front of me leaning his seat back quickly and breaking the MBA. No real point to this post, other than it got me thinking that I may opt for a new MBA 11" if they do a refresh soon. I normally fly business class for work travel, so not too big of an issue.. but I was slightly dissapointed that I had to sit awkwardly to use my MBA in coach class (Delta).
