I am very happy that you are satisfied, MelC. Unfortunately, I will not be elaborating further on opinions of Apple and/or the iPad. I have since sold it and purchased two devices that bring my wife and I more satisfaction. Now that makes three of us satisfied.
Thanks for your input.
For those who visit this thread seeking answers to whether an iPad apps can export annotations, the simple answer is "not as you would hope." iBooks will export notes through email (no highlights). Stanza will export one note at a time (no highlighting), but there is a high probability that development will not continue much longer with the app.
As of now, the iPad cannot perform the function of a device such as the Sony PRS line which can export a document with all your notes, highlights and scribbles with the click of a button.
Good luck to those seeking this feature and happy reading to those enjoying their iPads.
