Stevejnb, seriously? Caramilk or cream egg? You do realise it's alphabetical and K is next right?
You say "seriously" like that bit of trivia is common knowledge. I've owned three Android devices, read through multiple user's manuals on Android devices, read patch notes and product update notes, and probably several dozen news articles related to Android, and not once have I heard the alphabetical nature of their naming system mentioned.
So yeah, seriously. At least the alphabetical thing makes the name "kit'kat" make more sense, even if they did pick one of the most bland candy bars out there for the name.
