I picked up a Google Nexus 7 Tablet a few weeks ago, and I knew straight away I wanted a case to protect it. I also wanted a case that featured a “Smart Cover” facility; ie the ability to auto wake / auto sleep as the cover opened and closed (although not advertised with this feature, it was discovered the Nexus 7 had the support built into the hardware, and ever since, many of the 3rd party case suppliers have been supporting the feature).
So,was a logical choice (mainly for ease of purchase and keen pricing), and I selected this particular case as above; it acts as a Smart Cover case, but also can fold up to create a small stand for the tablet (it uses landscape, which the stock launcher doesn’t support, so look at purchasing Ultimate Rotation Control from the Play Store too, and setting it on Force Auto). The case provides protection around the back of the tablet (the tablet clicks into the back panel) and the cover works well. This particular seller provides this with a screen protector (currently untested) and stylus (tested and functional, and very similar to the cheap stylus you can pick up).
At £8 (price may vary) including shipping, I thought thewas good value; the case arrived within a couple of days, so I assume this is a UK seller too, and the choice of colours allows you to select one to match other devices or simply select black.
