So I've tried three cases now:
Poetic Turtle Skin
I stopped using the ProCase because I think it put a scratch on the screen.
I had two Poetic Revolution cases fail on me (the kickstand lugs are flimsy and break).
I got a Poetic Turtle Skin as a replacement after the second Revolution, and it is the best of the bunch.
Yep, it's true it doesn't have a stand built in (unless you want to sacrifice your stylus as a kickstand, which I don't want to risk). But the bumper case uses the same rubberized material as the old Poetic Commuter cases did. That means it's extra grippy, which means you can rest it on a pillow on your lap, and it doesn't slide off.
If you also have a hardware keyboard with a stand (like the Logitech Tablet Keyboard), you really don't need the built-in stand.
I would only recommend the ProCase if you really have your heart set on the magnetic screen close feature. The folio cover is not rigid enough to allow the tablet to stand on an unstable surface in landscape.
