received an i-Pad2 as gift and after 10 days returned same. Although Mac store advertised a "User Guide" for the i-Pad2, which was to be downloaded to my laptop, it failed to download. Mind you after I received a confirmationn from Apple to check my Laptop, there was no mail. Tried 3 times with same results. Got fedup with Apple, so took it back to store. After looking at the above comparison, I realize I should have kept the i-Pad2. Gave my son the i-Pad1 as a X-Mas/ birthday present. After thought Apple is now selling a book, All About the i-Pad2 for over $25.
