Check out this new case from Poetic for the Samsung Galaxy 7.0 Plus. I just got mine today, and it's just right for my tastes!
It's a black Poetic StandBook Stand Leather Case with Angle Adjustment. I found it on Amazon for $12.95 and free shipping. The ports, speakers, and cameras are all accessible with this case. The tablet is held in by small rigid curled edges on the corners and 2 extra curled edges on the short sides. The case itself covers only 2 tiny places on the glass, so the entire touch area is wide-open!
The cover part has a bit wider rigid curled edge that sort of snaps over the middle on the long side to keep the case closed. This curled edge covers the IR, so if IR is important to you, you can only use it with the case open... which... seems logical, anyway.
You can open the case completely. Turn the front completely behind the back of the tablet, and it lines up nicely behind the back cover.
You can see other features online if you look at pix on the Amazon or Poetic websites. This case has a really nice 'feel' to it. It's not a portfolio-type case, but is just what I've been looking for!
