I reviewed three cases and kept two of the three. The Poetic KeyBook Bluetooth Keyboard Case
which has the sleep/wake function and a removable keyboard. Unfortunately for folks now, I got this one when they weren't sure it was going to sell and it was only $15. I recommend this one if you want an all-in-one design. The case is secure, the keyboard is removable for times you don't want the extra weight and it offers good value (even now at $34) and protection for the device.

The second one I tried out was the Marware Vibe Standing Case
. I gave it a C+, my review here: Review of Marware Vibe Case
My favorite case, the Marware Lightweight MicroShell
. It is not perfect, but its perfect for me. It protects the case while adding almost no weight or bulk. My review is here: Review of Marware Lightweight MicroShell Folio Stand
I kept the Poetic and the Marware Microshell cases and am happy with both. I'll use the Poetic when I travel and use the Marware everyday. Neither of these cases is for you if you need your device to have a stand in portrait mode--even though the larger size is, IMO, better used in landscape mode.
I also bought a Logitech Bluetooth keyboard
that I leave at my desk for daily use. I really want a keyboard dock, but I guess the bluetooth will do while I wait.
I also protect the front of the device with a matte screen protector so I can use it outside and a skin just so it looks good and different from all the others out there.
