You Can Preorder an Apple Tablet on German Amazon (Update: Not Anymore.)
Likewise, on the stateside Amazon.com, all you can do is “Sign up to be notified when this item becomes available.”
A word of caution: the German iPads are pricy! They have the same pricing scheme as the American models — only in Euros instead of dollars. So: a $499 16GB iPad with Wi-Fi costs €499, a $729 32GB iPad with Wi-Fi and 3G costs €729, etc.
Inquisitr: “Apple has a tendency to believe that the Dollar and Euro basically is the same currency. It is NOT! 1 dollar costs 0.71 Euro. That means 1 Euro costs 1.41 US Dollars. So it is not ok to charge €499 for the “small” iPad, that Americans pay $499 for. That is a $200 price difference!”
If you want to take the plunge anyway, you can do it here.
