iPad availability in Germany

Today the selling of the Apple iPad started in Germany. The units are very rare in the shops, so unfortunatly not everyone can buy one. So my spontaniously idea to order or buy one direct in the nearest Apple store in Hamburg was break through unavailability of a iPad for me. So the process of analyse the need for buying and owning that device starts. Ok the same process had happened with the iPhone before I decided to bought it. The really best benefit of the iDevices is the astronomical (just a image ;-)) mass of Apps. Anyone with reallife experience and good advices ?
