BookArc for iPad ships with 2 inserts: Insert #1 comes installed and allows you to place your iPad in 4 different positions; vertical portrait or landscape and tilted portrait or landscape. Insert #2 simply adds a pad to the BookArc slot in an attempt to allow the use of any case that fits inside. Now that iPad is shipping and we’ve been able to test actual cases with Insert #2, we’ve learned that many cases tilt over when used with Insert #2. The solution is simple: just remove the silicone insert entirely. This allows most cases we’ve tested to work with BookArc for iPad just fine.
