Michael,

Your message says, "4) Also, an inflatable neck pillow is the road warrior's secret weapon. It holds your head still so you can fall asleep." The words "inflatable neck pillow" are linked to the Cloud-Soft Inflatable Pillow at Magellans.

Have you considered the inflatable Komfort Kollar (http://www.magellans.com/shopping/product/detailmain.jsp?itemID=742&itemType=PRODUCT&iMainCat=0&iSubCat=0&iProductID=742)?
Looks as though it might be even more comfortable.
