I have to ask. Is it common for anyone to type their country starting with characters inside of the word? I.e. instead of typing "can" for canada, would you type "ada" or something similarly fuzzy? I personally type "can", and if Canada is not the first result I consider it's usability inferior to a standard drop-down.
This example may not be ideal since this country selection has both "Congo" and "Congo, Democratic Republic of" in its data set, but the principle can probably be applied elsewhere.
