The Switch Easy was on my short list of cases and I'm glad I decided to go for it in the end. This is possibly the best case on the market for the new 3rd generation iPod Nano. I had no problems whatsoever inserting my Nano into the case; it fits perfectly with no play at all once inside the case. I did not bother with the click wheel protector as my Nano spends most of its time docked in my Intempo RDi speaker dock. Incidentally, the Nano can be docked in the RDi without removing it from the case - perfect! Which is just as well because the Nano is very difficult to remove from the case once it has been inserted. I also passed on the back protector as I see little point in this as the Nano is completely encased, anyway. The Switch Easy comes with a variety of accessories, which is always nice even if I won't be using them all.
The case looks very stylish indeed and I am confident it will do its job and protect my Nano from all but the most severe of damage. It adds virtually nothing to the overall dimensions of the Nano, which is great. In fact, some people have commented that they didn't even know my Nano was in a case! It really is that good. I had to turn the screen brightness up to 90% to make up for the slight darkness from the built-in screen protector, however, but this is not an issue for me as my Nano is usually on charge in the RDi.
I would imagine the case will end up with scratches if carried in a pocket or bag; the included cloth will get rid of minor surface scratches and greasy fingerprints but won't help with deeper scratches, so bear this in mind before throwing it in with your keys!
Overall, I would highly recommend this case, especially at £13 which is the best online price I have seen. (Other websites sell this case for about £18). Snap it up while you still can!
