Note that the OED does not offer "smilie" as a variant spelling--and
none of the cites examples there contain it. There is "smiley face" 2.
(1988 NYT) and "smiley" 1. (1987 ChiTrib) for the emoticon. The same
spelling exists for the other two entries as well (for the ubiquitous
yellow "happy" icon--e.g., see http://goo.gl/2G9FF for both "smilie"
and "smilie face") ["Smiley" also appears to be one of the local names
for Chinook or king salmon, but that's another story entirely.]
