Just trying to make the final decision on buying a MacBook air (likely the 11 inch version) and I'm trying to find out if anyone is using these on their tray tables.

I've found a few pics on google images that seem to indicate it'll be ok. At this size I figure it will be too, but since you guys are the biggest travelers I might as well just ask the experts.

Currently I have a 13" (it MIGHT be 15" I can't 100% remember) windows laptop and when opened I find it very cramped for a tray table, plus if the person reclines I'm kinda screwed.

It may be evident from my recline comment, but in case it's not, I'm specifically talking about cramped ole economy class. I figure if I'm good there then anything else would only get more spacious.
