I'm on my 4th rmini.
1st: week 44 (Foxconn) - fine, but returned
2nd: week 47 (Pegatron) - yellow tint on bottom 3rd; exchanged
3rd: week 43 (Foxconn) - yellow tint on bottom 3rd; exchanged
4th: week 43 (Foxconn) - blue hue along edge on top and sides; backlight bleeding in lower left hand corner
I might try to just deal with the blue hue; it's better than a yellow tint and I'm concerned that if I do another exchange, I'll receive another one with with a yellow tint. Plus, Apple employees have looked and treated me like I was a little odd for complaining about the tint. On my first exchange, an Apple employee felt the need to lie to me - he told me that I was receiving an iPad that was made in the US. I said, no it wasn't. He said yes it was, and was made by a technician to ensure that it had no issues. This was in the Burlingame store. I didn't really appreciate being lied to.
