New A/B Test for Your Vote: Popup or Slider Email Subscription Widget?

Can you guess which email subscription widget, popup or right column slider, got 59% more email subscriptions?

Please note that the email subscription widget was displayed only on the visitor’s fourth product view. The email subscription forms were identical, it’s only the method of displaying them that varied between Version A and Version B.

See if you can pick the winner and then post your comments:
