I'm using the Logictech Ultrathin keyboard iPad cover. And yep- I love it. I'd have to say that it must frustrate some Apple tech who put unknown hours into the touch screen so that I could add 1980s tech to make it larger! But still- w/o this keyboard I probably would have returned the iPad.
Anyway- Correct me if I'm wrong but isn't the cover supposed to magnetically bind when closed? Not at the hinge- that is still functioning properly but when folded closed as a book it just opens w/ zero resistance. I'd thought there was some light magnetic resistance that helped it stay closed.
