I'm gonna chime in here. I was in China for a month, went on Taobao which is the Chinese version of ebay for a 1020 case hunt. To me the old official nokia 920 is perfect - it offered great protection, adds grip, comes in a bunch of colors and fitted like a glove. I love to be able to just put down my 920 on any surface without the need to be gentle.
Nokia somehow decided that the 1020 doesn't deserve such a case and I was left with trying to find something similar. I've went case testing and bought about 20 different styles. The soft TPU ones were of horrid quality, and broke the clean design of my 1020. The hard cases were all made from polycarbonate, which is good in that it came in a variety of colors, but I gave up since it is just as slippery and a phone with no case. The Nilikin case is one such case. In the end I've settled with this:
It's about $2AUD when converted from RMB and it has:
superior grip - it features a sandy textured surface
fingerprint and smudge proof - due to the surface again
decent protection for the back of the phone
can be taken off and put back on again in an instant so I can go grip case to camera grip in <10sec (when on it's tight so there is no chance of it slipping off)
In the end, I've bought all the colors and stocked up on a 2nd backup gray because it is my favourite (have a gray 920

)
alas, it is still quite hard and doesn't offer much shock protection. I can't toss my 1020 on the table like the old 920:unhappy:
