I have the Yoga3 on it's way, and looking at cases with an auto sleep/wake ike my Poetic case did for my Nexus 10. Few on Amazon.ca say they do, then in the reviews the customer comments say no, they don't. I can't seem to see if this tablet support wake/sleep function from a case? If so... any idea where I can get this style case with the option? I don't want a case where the tablet sits inside and the case has a frame around the screen, that'll just get in the way. This seems like what I want, but I'm in Canada... no one seems to sell it.
