I've thought about it on every recent flight. I never used to be able to sleep on planes, but years of less-than-stellar sleep has cured me of that issue. Now I can sleep anytime, anywhere.
So do I buy a neck pillow? I've finally taken the plunge.
Technically, I hate having things around my neck. It's just too claustrophobic for me. Plus, I like packing light. Carrying around something like this on a business trip seemed silly. On a vacation? Even sillier. But I've got a 14 hour each way fight coming later this month, and I *know* I need to sleep then. And for $15, how wrong can I go?
I'll let you know in a few hours when I get back home. :)
