After missing delivery Friday, I received my 128 GB Silver AT&T rMini today. I immediately powered on and performed the yellow tint and retention test. The yellowing appears to not be present but image retention is. I boosted the brightness to 100% and sat on the checkerboard image retention page for 3 minutes then switched to grey. It was there. However, it only lasted 20-30 seconds in each of the 3 tests. There is no way my local store has 128GB cell models so undoubtedly they will tell me they would have to order it even if willing to replace it. To me, my Macbook Pro Retina is for my videos and pictures. My iPad Air is for games and other stuff when not with my Macbook. The rMini is for reading books and other easily-traveled items when I just want it in my pocket. So, honestly, maybe not worth it. Anyone with similar situation decide it is not worth replacing?
