One other cool aspect of Google authenticator; it's not tied to Google Accounts. When I had two factor for a work Office 365 account I used the gauth app for my codes. In fact, O365 support docs instructed me to do so.

I mean, in one corner we have vaguely manly/futuristic/open and free (longhorn, XP, Vista, the latter being particularly notable), and in the other you have the uber-hip-sleekness of large jungle cats. Personally, I would much rather an OS comapny has a little fun with their name, but they don't sweat it too hard, rather than spending millions on focus groups/marketing/product positioning. Particulaly when that money could be better spent on QA.
