Astounding. Only one appropriate response. Send it back, get a full refund (protest the charge on your credit card if you must) and go shopping for an Android Tablet.
I'm not being sarcastic. Honestly the war stories of how badly Apple is handling the iPad2 production and launch makes me more than concerned about my April 1 shipdate order. I swear if it comes to me defective, I'm gonna do exactly what I said. I have an iPad1 and Touch I can play with in the meantime. And frankly the ability to use Flash, have expandable memory and a quality camera are MUCH MORE appealing to me than a shoddy product from a too-big-for-its-britches hipster company.
FWIW I do empathize with your fury. Apple is most definitely NOT handling their customer service well right now. Hope the store exchange works for you. If not, return and get a full refund. Punish Apple by not giving them your heard-earned money.
