I would definitely like to see a water proof case for the Adam.
I see someone plans to take Adam for a swim . For a waterproof case, something like TrendyDigital's Waterguard Plus case for the iPad would work well. (picture below)
Two types of cases which should be available for Adam immediately upon release are something similar to AidaCase's Keycase Folio Deluxe for the iPad, which is a keyboard, case, and stand; and Otterbox's iPad Defender case, for those of us who will use Adam in tough environments.
I like the Oberon cases. They are a little more expensive than other brands, but they are gorgeous. I like also the idea with a book. Pad & Quill, M-Edge and DodoCase have cases for iPad and Kindle that look like a leather covered book (but they are not as beautiful as Oberon ones). Hopefully at least some of them will make some cases for Adam.
