After purchasing my Nexus 7, I wanted a case to keep it brand new and shiny. I often buy cases for my electronics; I use them for a few weeks, then get bored and decide that the case acted only as a hindrance. I do this quite a lot.
There are 1000’s of cases on the market of different shapes and sizes, all claiming to do different things. For me, the main thing is protection. When looking for a case, I was looking for something perfect for use when travelling. To be honest, when I’m just using the device in my house, I don’t really want a case, and I dislike that most of the time, it seems that to protect any electronic device, you end up sacrificing the aesthetics of the product. I’ve messed about with various types of cases that aim to protect the product with minimal aesthetic interference, but these often only protect the rear of the device, when in reality the most delicate part of any tablet or phone is the screen.
