I never did come back and report on my experience once going to the apple store, so here it is:
To review, my ipad had the exact same bend in the exact same place as the OP and to my knowledge, it had not received an impact or compression of any kind (brand new after all).
When I went in, they were rather rude about making the appointment with the genius bar (but that is a different story alltogether & may have just been the employee having a bad day). Once I came back on a later day, I showed the bend to the apple employee explaining that I don't believe this was caused by impact and offered to show him that I'm not the only one with this concern (this forum), he simply stated "I'll have to check if this is covered by the warranty" (again still under initial warranty since it was new). He took the ipad and walked to the back with it. When he came back he said without emotion of any kind "I checked and the frame bending is covered by the warranty on phones but not on ipads." He then went on to tell me how lucky I am that I have the apple care plan. While he deserved to be shot for really not thinking that the customer in front of him isn't happy to be there at all, let alone to be being told that he has to pay more to get a product that should have been reliable already, I'm sure he meant well.
So $50 later I got a "remanufactured" ipad (which is apparently the exact same thing as refurbished except they don't reuse external parts to make sure there are no scratches visible... he was very insistent that they are not the same thing).
How I would rate this experience 2/10... which is unfortunate because I've long been an advocate for the service quality of apple. I haven't had to use it much but before now all I've had were good experiences.
So far it is working fine and I have put it in a case that is strong of its own accord so even if the device is inclined to warp itself, it has something external to help hold it's shape. When windows mobile devices become more viable, we'll see if I stick with apple or not. After all, if they don't have service going for them anymore, they are becoming more and more like other electronic manufacturers.
