I'm pretty sure mine arrived defective. I was out of town the weekend the 3g came out, but I had it shipped to me. I wasn't able to play with it much until the following sunday, when I noticed a scratch. When I got back home I took it to an apple store and the repair dude was super patronizing when insisting that I scratched it vs it arriving defective, "I wish I could go back in time with you..." He also claimed that anything can scratch the ipad, including keys, as it is "just glass".
When I got home, I took a flashlight to the screen when I noticed another scratch catch my eye, and noticed 10+ scratches.
Long story short, I live in NYC so I went to a different apple store (boo 5th ave!), was told that I should return it via the online store, and one should be shipped to me soon.
Lessons:
-Carefully inspect new iPads right away, check with flashlight. I would imagine those minor scratches could be like cavities waiting to grow.
-IF it truly did not arrive in poor condition and I was at fault, then at least some of these ipads are very sensitive. I had an apple case, don't wear a watch or jewelry, and only had the device for a day and half.
BTW, one of the first things I did with my ipad was activate a 250mb plan. It took a non-trivial amount of time to convince apple that Yes I should keep the sim card No I shouldn't cancel my existing AT&T plan Yes that would be easier for you but not for me.
Now I'm wondering if I need a screen protector or not, despite the fact that I most probably did not cause the damage.
