I have tried 3 cases for the new Nexus 7, all from Amazon.

Poetic Slimbook - stiffener in spine makes it so rigid that it's difficult to fold it open like a book, stylus loop is on the back not side, tablet tends to work itself out just enough to make swiping difficult (there is no velcro to secure the flap holding the tablet in). The fit is good and everything is easily accessible. Magnetic on/off closure works fine. A little heavy at 5.4 oz.

Poetic Slimline - Nice light case (3.8 oz) and the tablet fits snugly and securely in the frame. The drawbacks to this case are that it offers little protection in a fall, and the magnetic on/off mechanism is unreliable, choosing when it wants to work or not.

Caseology Ultra Slim Fit Leather Multi-Angle Stand Case - Nice case overall, good fit, well made and has velcro to secure the tablet's hold in flap. It folds open nicely because the spine is flexible not righd. It's has no stylus holder but not a big deal. But this case is near useless because access to the power and volume buttons is virtually impossible. The cutout really doesn't expose the buttons.

So there you have it. Three case down and still looking for one that has it all. Any suggestions?

Is there some way to turn off the 3G and still be able to use wifi? I would like the assurance that I'm not wasting any of my limited 3G data plan where there is wifi. Airplane mode kills both 3G and wifi so that doesn't do it. I could just remove and replace the SIM card, but that's painful to do all the time. Is there no switch in settings to toggle 3G?
