picked up my 32 gig N7 at walmart yesterday. Mine has the rubbery grippy back as well. not hard plastic.
Rooted, updated to 4.2 and as of a few hours ago, Chainfire updated Stickmount and added stickmount pro to the market place to "buy him a beer" (and adds some extra features) so based on the feedback on XDA so far, OTG is up and running once again.
So far, I really like mine. I'm waiting for my OTG cable/case/screen protector to show up but so far, everything is working great and a HUUGE improvement over my HTC glacier running a custom gingerbread rom.
It's my first tablet so I'm still very much in the discovery phase of the device essentially using it and seeing how it fits into my life or how it will change how I do things. I can already tell I'm going to enjoy playing emulators with the 360 controller though. The actual android market games I'm seeing are ok but nothing compared to a good old SNES classic.
We got my wife an ipad 4 Friday for her work and to replace an ancient casual web browsing/skype laptop she's using and she's already glued to the thing.
Started using my Nexus 7 as a multimedia/navigation/boardcomputer in my car:
I love how multi-faceted my use of the device has become. I literally use it everywhere now :lol
Which app are you using for that?
