I got my iPad as well from Burlington Mall Apple Store (MA). 16GB black 
However my unit also has the leakage issue at the bottom. I will use it as an excuse to replace the unit when I feel the time is right. In the meantime the unit works perfectly fine.
I don't care much for the smart cover either due to it not sticking to the back. Most of my time has been without case.
The thinness is truly the killer feature. It is magazine thin and book heavy. Very impressive.
