Do you mind doing a quick comparison between the Mcdodo and Anker when you get them?
In another thread I saw this one:
http://www.nillkin.com/english/proshow.asp?mid=2&sid=0&tid=0&cid=1&scid=13&id=4512&page=2
It looks almost the same as McDodo, but has textured sides for "added grip".
To me, it looks like most of these thin cases are pretty much the same with the variation being any branding, the cut out of the speakers, dust covers, or other minor things. I have a cheap one from ebay (~0.80) and it looks almost the same as these 2. I'm mostly interested in the dust cover and the added grip.
